-Known issues with the UP1000 system:
-
-1. Linux boot via floppy disk drive:
-        When booting Linux via APB, it takes about 5 minutes for APB to load the kernel image from a floppy device. 		Booting from a hard disk takes a matter of seconds.
-
-2. 2x AGP card:
-        a. At the present time, 2x AGP driver for Linux is not available so 2x mode has not been tested.
-        b. The following cards have been used in 1x AGP mode: cards with Permedia-2 controller: Fire
-	GL1000, ELSA Synergy, E&S, Matrox Millenium G200 and Stealth 2000.
-        c. 3Dfx Rage Pro Turbo card does not work because the option ROM on the AGP card is
-	not properly emulated by Alpha BIOS.
-
-3. Linux installation:
-	a. To install Linux, please click the  "Utilities" menu in the Alpha BIOS setup mode and the 
-	"Run Maintenance Program". And follow the Linux installation procedure that API provides. 
-	b. Please do not use the "Install Linux" menu in the "Operating System" menu.

-- Installation of RedHat Linux from CD ROM
-
-1. Copy this directory to a floppy disk.
-
-2. Insert floppy disk and RedHat Linux CD ROM.
-   This installation guide assumes 
-   - hard disk is connected to primary channel as a master 
-   - CD ROM drive is connected to primary channel as a slave 
-
-3. From AlphaBIOS run apb.exe as a utility program.
-   [F2]->Utility->Run maintanace program
-
-4. At the apb command prompt, type
-     apb> cd floppy
-     apb> bootl up1000.pal vmlinux.gz root=/dev/hdb
-   This assumes you have an ATAPI CD ROM drive which Linux recognizes
-   as /dev/hdb (you may have to try /dev/hda, /dev/hdc, etc. depending
-   on your configuration.  For a SCSI CD ROM drive,  /dev/scd or
-   /dev/scd0.
-
-5. This should get you into the RedHat installation program. During the
-   disk partitioning phase of the installation be sure to allocate a small
-   FAT partition to be used as the "boot" partition.  10 MB should be ample.
-   If you choose 'Workstation' or 'Server' package then you don't need to
-   partition the disk by yourself. 
-   * Follow the common redhat installation procedure.
-   * During install, Don't configure X server,
-   * Select 'Startup through ARC console' on timezone setup menu.
-
-6. Due to bugs in redhat 6.0, FAT partition is not formatted during installation
-   depends on package selection.
-   So, After installation, run apb.exe from flopy again and at the 
-   apb command prompt, type
-      apb> cd floppy
-      apb> bootl up1000.pal vmlinux.gz root=/dev/hda5 single
-   You'll get shell prompt then type following commands.
-      # mkfs -t msdos /dev/hda1
-      # mount /dev/hda1 /dos
-      # mcopy a:*.* /dos
-      # gzip -dc /dos/system.gz > /boot/System.map
-      # ln -s Tsunami /etc/alpha_systype
-      # init 6
-
-8. Configure the OS selection menu of AlphaBIOS to start apb.exe
-   from the boot partition.
-   In 'OS Selection' menu([F2]->Operating system->OS selection setup), 
-   Make an entry like this.
-
-       Boot name: Linux
-       Boot file: Disk 0 Partition 1   \apb.exe
-       OS Path  : Disk 0 Partition 2   \winnt
-       OS Options:  
-
-   OS Path doesn't have any meaning, just leave it intact.
-
-9. You can run apb from hard disk by selecting what you configured on step 8.
-
-10. Set the environment variable APB_DEVICE to be the AlphaBIOS name 
-   of the boot partition.
-   For example,
-      apb> setenv APB_DEVICE scsi(0)disk(0)rdisk(0)partition(1)
-   type 'cd' once to make above environment variable change to be applied.
-      apb> cd
-
-11. Now, You can boot linux by selecting 'Linux' on BIOS' OS boot menu 
-   and then type this on apb prompt
-
-      apb> bootl up1000.pal vmlinux.gz root=/dev/hda5 
-
-   If you don't want to type above long line everytime. You have two options
-	1. Create apb.cfg file under /dos directory, Its contents look like
-
-		linux|bootl up1000.pal vmlinux.gz root=/dev/hda5
-
-	   then you can boot linux by typying 
-
-	      apb> boot linux
-
-	2. Put option string in OS Selection setup menu of BIOS setup.
-
-	       Boot name: Linux
-	       Boot file: Disk 0 Partition 1   \apb.exe
-	       OS Path  : Disk 0 Partition 2   \winnt
-	       OS Options: bootl up1000.pal vmlinux.gz root=/dev/hda5
-
-	   Then this setup will boot linux without apb prompt.

-
-0. Introduction
-
-APB is a bootstrap loader for Alpha processor based systems with
-AlphaBIOS firmware.  It is primarily intended to be used for booting
-Linux, though it may also be useful for free BSD derived systems.
-
-APB borrows ideas and some code from many places, notably Linux and
-other Linux loaders for Alpha systems (aboot and MILO), and the ARCDos
-example in the ARC Application Development Kit.  APB can also be
-linked against zlib to support reading compressed kernel and PALcode
-images.  See the file CREDITS for details.
-
-
-1. Using APB
-
-+ Overview
-
-APB presents a simple command line interface with the following
-commands
-
-  boot TARGET                   boot a target in the configuration file
-  bootl PALCODE KERNEL ARG1 ... boot Unix
-  cd DEVICE                     set the current device
-  cp | copy FILE1 FILE2         copy files
-  exit | quit                   exit to AlphaBIOS
-  halt | reset                  system shutdown options
-  ls | dir                      list files on the current device
-  mkdir DIR                     make a directory
-  more FILE                     list a file
-  mv | rename FILE1 FILE2       rename a file
-  pwd                           print the current device
-  rm | delete FILE              delete a file
-  printenv [NAME]               print environment variable(s)
-  setenv [NAME [VAL]]           (un)set environment variable
-  show targets | devices        show information
-
-At any time an AlphaBIOS is device is selected as the default or
-current device.  On initialization this is set to the value of the
-APB_DEVICE firmware environment variable, or "multi(0)disk(0)fdisk(0)"
-(usually the floppy device) if this is not set.
-
-To change the default device, use the "cd" command. For example
-
-  cd scsi(0)disk(0)rdisk(0)partition(2)\os\linux
-
-sets the default device to be the second partition of the disk 0 on
-the 0th SCSI controller.  To save this for future invocations, set the
-APB_DEVICE firmware environment variable using the "setenv" command:
-
-  setenv APB_DEVICE scsi(0)disk(0)rdisk(0)partition(2)\os\linux
-
-After this you can return to this device using "cd".
-
-Also the special targets
-
-  cd floppy
-  cd cdrom
-
-will take you to the (first) floppy and CD-ROM drives respectively.
-
-If there is a file system supported by AlphaBIOS on the device -- FAT,
-ISO 9660 (CD-ROM) -- then a directory listing can be obtained using
-the "dir" or "ls" command:
-
-  apb> ls
-  Directory listing of scsi(0)disk(0)rdisk(0)partition(2):
-  APB.CFG
-  APB.EXE
-  LINUX.PAL
-  VMLINUX
-  
-
-+ Booting from disk
-
-The recommended way to boot a system using APB is set aside a small
-(10 - 30 MB) FAT partition on one disk to be used as a boot partition.
-The following files should be placed on the boot partition:
-
-  The APB image (APB.EXE)
-  The PALcode image
-  The kernel image
-  An optional configuration file "APB.CFG" (see below)
-
-Run APB (either from floppy or from the boot partition and use it to
-set the environment variable APB_DEVICE to the name of the boot
-partition.  For example if the boot partition is the first partition
-on a SCSI disk with SCSI ID 3 on the first SCSI controller, and the files are in directory \os\linux set APB_DEVICE using
-
-  apb> setenv APB_DEVICE scsi(0)disk(3)rdisk(0)partition(1)\os\linux
-
-To enable autoboot
-
-  apb> setenv APB_AUTOBOOT 1
-
-This performs the first boot command it finds in the APB configuration
-file, unless interrupted.
-
-Otherwise boot manually using a command such as
-
-  apb> bootl palcode kernel [kernel_arg1 [kernel_arg1 ...]]
-
-or use one of the labels defined in the APB configuration file, for
-example
-
-  apb> boot linux
-
-See below for the configuration file format.
-
-+ Environment variables
-
-APB uses the following firmware environment variables to set default
-noptions:
-
-  APB_DEVICE            Default device for all operations
-  APB_AUTOBOOT          Determines whether an autoboot should be attempted
-
-If these are not set on invocation, then they are set to reasonable
-values, namely
-
-  APB_DEVICE=multi(0)disk(0)fdisk(0)
-  APB_AUTOBOOT=0
-
-+ Configuration file
-
-APB consults a configuration file "APB.CFG" that is assumed to be
-located at the current device path (initially given by environment
-variable APB_DEVICE).  The file consists of lines that are either
-comments, or boot commands prefixed with a mnemonic label. For example
-
-  # This is comment
-  linux-2.2|bootl linux.pal vmlinux.gz root=/dev/sda3
-  linux-2.0|bootl linux.pal vml20.gz root=/dev/sda3
-
-In this case, to boot linux-2.2, type
-
-  apb> boot linux-2.2
-
-which is equivalent to
-
-  apb> bootl linux.pal vmlinux.gz root=/dev/sda3
-
-If the AUTO_BOOT environment variable is set TRUE, then the default
-configuration will be booted after 10 seconds, unless a key is
-pressed.
-
-+ Boot devices
-
-APB can boot from any filesystem supported by AlphaBIOS.  At present
-these are limited to FAT, NTFS and ISO 9660 (CD-ROM).
-
-+ Booting from a network device
-
-Not yet implemented.
-
-
-2. Building APB
-
-APB is an AlphaBIOS/ARC application.  Currently it must be built on an
-Microsoft Windows NT 4.0 Alpha processor system, with Microsoft Visual
-C++ 5.0 (or higher), the Microsoft Software Development Kit (SDK) and
-Device Driver Development Kit (DDK) for NT 4.0, and Compaq ARC
-Application Development Kit (ADK) 1.3.
-
-Optionally, APB can be linked against zlib (a free compression
-library) to support reading compressed kernel and PALcode images.
-
-To build, open a command window, set up the environment:
-
-  VC++ (e.g "C:Program Files\DevStudio\VC\bin\vcvars32.bat")
-  DDK (e.g. "C:\DDK\bin\setenv.bat C:\DDK")
-  ADK (e.g. "set ADK=C:\adkv13\adk")
-
-and then and make using nmake.  For example:
-
-  C:\apb-1.0> nmake
-
-where the DDK has been installed on the C: drive.
-
-If building with compressed file support, obtain and unpack zlib
-(http://www.cdrom.com/pub/infozip/zlib/), set the variable ZLIB to
-the zlib directory, and then make.  For example
-
-  C:\apb-1.0> set ZLIB=C:\zlib-1.1.3
-  C:\apb-1.0> nmake
-
-In either case, the executable is placed in the "obj\alpha"
-subdirectory.
-
-
-3. What APB does
-
-Booting Linux with APB involves the following steps:
-
-  AlphaBIOS loads and transfers control to APB.
-  
-  APB is called with an argument specifying the device (as known to
-  AlphaBIOS) from which to read the Linux kernel, and additional
-  arguments to be passed on to the kernel.
-  
-  APB sets up the environment for Linux, including loading and
-  switching to the correct PAL code, setting up the HWRPB, copying
-  kernel arguments to the right location in memory etc.
-  
-  APB reads the Linux kernel image into memory from the specified
-  device (raw disk initially, and eventually filesystems or network
-  devices via bootp) and transfers control.
-
-
-4. Modifying APB
-
-APB has been written with the aim of maintaining platform independence
-across all AlphaBIOS (and ARC) systems.  Furthermore, all dependence
-on the ARC API has been isolated in the file "arc.c", so that porting
-to another firmware environment should not be too difficult as long as
-it provides a sufficiently complete API.
-
-Additional user commands can be incorporated through the command
-dispatch table in "cmd.c".

+
+This is a preliminary version of a VGA softbooter for LINUX.
+
+It makes use of the of the vm86() call and is therefore only
+usable on ix86 systems. 
+There are plans to port this program to use a x86 emulator
+like x86emu. Also it may be ported to other operating systems.
+
+So far it has been tested on a small number of cards. It might
+well be that it will fail on your card. 
+
+If you need to make modifications to the programs to be able
+to boot your card please let the author know.
+
+So far there is no command line interface. All options need
+to be hardcoded. You can do this by editing debug.h. You can
+turn on a bunch of debug output. Other options allow you to
+boot the primary card (CONFIG_ACTIVE_DEVICE), save the bios
+to a file (SAVE_BIOS), and map the original system bios 
+(MAP_SYS_BIOS).
+
+The author wants to thank
+ Hans Lermen   (dosemu)
+ and
+ Kendall Bennett (x86emu)
+for their support. 
+
+Parts of the code - especially in v86.c and io.c - are based on code
+taken from dosemu. Parts of the code in int.c are based on code taken
+from x86emu

+	fs segment override
+	gs segment override

+*
+* Description:  This file includes subroutines to implement the decoding
+*               and emulation of all the x86 processor instructions.
+*
+* There are approximately 250 subroutines in here, which correspond
+* to the 256 byte-"opcodes" found on the 8086.  The table which
+* dispatches this is found in the files optab.[ch].
+*
+* Each opcode proc has a comment preceeding it which gives it's table
+* address.  Several opcodes are missing (undefined) in the table.
+*
+* Each proc includes information for decoding (DECODE_PRINTF and
+* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc
+* functions (START_OF_INSTR, END_OF_INSTR).
+*
+* Many of the procedures are *VERY* similar in coding.  This has
+* allowed for a very large amount of code to be generated in a fairly
+* short amount of time (i.e. cut, paste, and modify).  The result is
+* that much of the code below could have been folded into subroutines
+* for a large reduction in size of this file.  The downside would be
+* that there would be a penalty in execution speed.  The file could
+* also have been *MUCH* larger by inlining certain functions which
+* were called.  This could have resulted even faster execution.  The
+* prime directive I used to decide whether to inline the code or to
+* modularize it, was basically: 1) no unnecessary subroutine calls,
+* 2) no routines more than about 200 lines in size, and 3) modularize
+* any code that I might not get right the first time.  The fetch_*
+* subroutines fall into the latter category.  The The decode_* fall
+* into the second category.  The coding of the "switch(mod){ .... }"
+* in many of the subroutines below falls into the first category.
+* Especially, the coding of {add,and,or,sub,...}_{byte,word}
+* subroutines are an especially glaring case of the third guideline.
+* Since so much of the code is cloned from other modules (compare
+* opcode #00 to opcode #01), making the basic operations subroutine
+* calls is especially important; otherwise mistakes in coding an
+* "add" would represent a nightmare in maintenance.

+*
+* Description:  This file contains the code to implement the primitive
+*				machine operations used by the emulation code in ops.c
+*
+* Carry Chain Calculation
+*
+* This represents a somewhat expensive calculation which is
+* apparently required to emulate the setting of the OF and AF flag.
+* The latter is not so important, but the former is.  The overflow
+* flag is the XOR of the top two bits of the carry chain for an
+* addition (similar for subtraction).  Since we do not want to
+* simulate the addition in a bitwise manner, we try to calculate the
+* carry chain given the two operands and the result.
+*
+* So, given the following table, which represents the addition of two
+* bits, we can derive a formula for the carry chain.
+*
+* a   b   cin   r     cout
+* 0   0   0     0     0
+* 0   0   1     1     0
+* 0   1   0     1     0
+* 0   1   1     0     1
+* 1   0   0     1     0
+* 1   0   1     0     1
+* 1   1   0     0     1
+* 1   1   1     1     1
+*
+* Construction of table for cout:
+*
+* ab
+* r  \  00   01   11  10
+* |------------------
+* 0  |   0    1    1   1
+* 1  |   0    0    1   0
+*
+* By inspection, one gets:  cc = ab +  r'(a + b)
+*
+* That represents alot of operations, but NO CHOICE....
+*
+* Borrow Chain Calculation.
+*
+* The following table represents the subtraction of two bits, from
+* which we can derive a formula for the borrow chain.
+*
+* a   b   bin   r     bout
+* 0   0   0     0     0
+* 0   0   1     1     1
+* 0   1   0     1     1
+* 0   1   1     0     1
+* 1   0   0     1     0
+* 1   0   1     0     0
+* 1   1   0     0     0
+* 1   1   1     1     1
+*
+* Construction of table for cout:
+*
+* ab
+* r  \  00   01   11  10
+* |------------------
+* 0  |   0    1    0   0
+* 1  |   1    1    1   0
+*
+* By inspection, one gets:  bc = a'b +  r(a' + b)

+* Description:  Program to validate the x86 emulator library for
+*               correctness. We run the emulator primitive operations
+*               functions against the real x86 CPU, and compare the result
+*               and flags to ensure correctness.
+*
+*               We use inline assembler to compile and build this program.

-Mini-Howto on burning Mandrake PPC Bootable CD's for Apple G3/G4 systems
--------------------------------------------------------------------------
-email: John Buswell <johnb@mandrakesoft.com>
-
-To create a disk image simply use the mkINSTALLCD script provided in this
-directory. The path you provide the script should point to the root directory
-for the CD.
-
-For example after you have built the gi install with /export, simply pass 
-/export to the script as the distribution path and a name for the image.
-Once the image is built you can use hmount, humount, hdir, hcd and hattrib
-to modify and inspect the image before you commit it to CD-R.
-
-Before you run the script make sure the CD version of iBoot is in the 
-iBoot directory below /export (eg. /export/iBoot), if you want to use some 
-other directory then simply modify the script. Beware, HFS is not case
-sensitive, so if you already have an INSTALL file you cannot create install.
-
-Currently iBoot sports two trees, one for the install CD and another for
-regular usage. These will be merged shortly and a simply #define can be used
-in the Makefile to implement one or the other from a single binary.
-
-Enjoy!!
-
-
-Addendum:	3/15/2001  Stew Benedict <sbenedict@mandrakesoft.com>
---------------------------------------------------------------------------
-
-A couple of changes.  
-
-I've opted to standardize on yaboot, which is user configurable, so the script 
-is modified now to use yaboot.
-
-Secondly, since mkhybrid merged with mkisofs, the hybrid images it creates are 
-read-only, so one is unable to mount the image and bless the boot directory for
-booting.  Consequently, I've included the binary for mkhybrid-1.12b5.4, which
-does work.
