IN-2000 BIOS version VCN: 887-01.3
__________________________________

This version of the BIOS has several new features:

  -  Support for more than two hard drives under DOS is now automatically
     enabled by the SCSI BIOS (no more confusing switch changes).

  -  Supports hard drives up to 8 GBytes formatted capacity 
     (9.6 GB unformatted).

  -  Supports most popular translations used by other SCSI manufacturers, so
     you can replace other SCSI adapters with the IN-2000 without having to 
     re-format the SCSI hard drives.

  -  BIOS now lists all attached SCSI devices by model and firmware versions 
     during boot-up.

  -  <Esc> hot key option at BIOS post time that jumps you directly into the 
     IN-2000 diagnostics.  After exiting diagnostics, system continues booting
     normally.

  -  SCSI hard drives are not required to be set for consecutive SCSI IDs, 
     starting with ID 0.  Example: three hard drives at IDs 2,3 and 5.  You 
     will be able to boot to the drive at ID 2 and access all three drives.  
     You may then remove the drive at ID 2 and then boot to ID 3! (providing
     the drive at ID 3 is a bootable drive)

The following bugs from the VCN: 1-03 BIOS have been fixed:

  -  The "disk block size invalid" error comming from SCSI tape or CD-ROM.

  -  The lack of support for the hard disk spin-up command during BIOS post.

You must use ASPI manager versions of VCN: 461-13.14 or greater with this
BIOS version.

NOTE: This version of the BIOS and all future releases no longer support the
old IN-2000 SCSI shell programming code.  As a result, programs that were
on that code will no longer work. Some of these programs are: IN2000.EXE,
INUTIL.EXE, the old Sytos Plus drivers and old, non-ASPI versions of NovaBack.

        The EPROM checksum for this BIOS is: CE00
        The DIAGNOSTIC checksum for this BIOS is: DC00

    THE FOLLOWING NOTES ARE NOT PART OF THE ORIGINAL README.TXT

Chip Requirements:

    The BIOS EPROM should be a 27C128, any manufacturer, with a speed
of 200ns or better.

    The firmware is a little trickier. It is to be programmed into a
specific serial PROM (SPROM), manufactured by Xilinx, Inc. No substitution
of parts is allowed, as the IN-2000 uses a proprietary Xilinx chip for its
main logic. Said chip requires the following.

    Xilinx XC1736DP, should be obtainable as a single-quantity sample
by contacting Xilinx at 408-559-7778. Be aware that they may refer you
to a distributor to obtain samples. If the chips are purchased
wholesale, they run approximately $6.30 each.

    Where the EPROM can be programmed with just about any EPROM or
device programmer, the Xilinx chip is very picky about algorithm and
programmer. The one I've used to program it is a Data I/O UniSite with
the SITE 48 programming module and version 4.9 or later software.

    If you do not have access to a UniSite, Xilinx may well be able to
provide programming instructions.

    The files are in Absolute Binary (Data I/O #16) format, and are
named as follows:

        BIOS: IN2KBIO.BIN
        SPROM: IN2KFW27.BIN

    Best of luck!
