- TITLE: ABIOS problems on RAM Loadable ABIOS systems
-
- At the time of this writing the RAM loadable ABIOS systems are:
- PS2s 9556/9557; 9585; Thinkpad 700/720 and the 9553.
- Some of the newest PS2 9577 systems may also be RAM loadable ABIOS.
-
- To install OS2 2.0 on these systems get or make a reference disk
- specific to the system. On the reference disk you will find the
- files ABIOS.SYS and ????????.BIO (where ???????? is specific name
- .BIO file for that system) and copy these files to the OS2 Install
- disk and disk 1.
-
- To install OS2 2.1 on these systems copy the ABIOS.SYS and the
- ????????.BIO file from the reference disk to the OS2 Install disk.
- Note that if the system is a PS2 9556 or 9557 this procedure is
- not necessary with OS2 2.1.
-
- If problems continue on the system, boot from disks to a command
- prompt and look on the system hard drive in the root directory and
- the \OS2 for any copy of ABIOS.SYS that may exist and delete it.

- CID and RAM Loadable ABIOS systems.
-
- When installing OS2 v2.1 on a PS2 9556/9557, the BASEDEV
- statement IBM2M57.ADD handles the ABIOS problem. This statement
- should be in the CONFIG.SYS of the CID boot disks. You should
- also have a DEVICE=\REFPART.SYS in the CONFIG.SYS.
-
- There are several ways to get around the ABIOS problems of the
- RAM loadable ABIOS machines. First you must make or get a
- reference floppy disk for the machine. On the reference disk you
- should find an ABIOS.SYS file, a ABIOS.DDP file, and a *.BIO file.
- The official way is to use the DDI* response file keywords. You
- will find the needed files for DDI* keywords on the reference disk.
- You should create a separate directory on the server to put the
- ABIOS.DDP, *.BIO, and ABIOS.SYS file from the reference disk in.
- Reference the redbook GG24-3780-02 page 108-109, 143-145
- for information. This procedure requires that you use a custom
- response file for these machines. This response file will not work
- on other machines.
- Also see the SAMPLE.RSP file for information about DDI* keywords.
-
- Another way to fix ABIOS problem is to modify the ABIOS.SYS files
- on the CID boot disks and the CID server disk images. Find the name
- of the *.BIO file on the system reference disk and put that name at
- the top of the ABIOS.SYS files on the CID boot disks and on the CID
- server OS2 disk images. For OS2 2.1, the ABIOS files are on the
- Install disk which is known as DISK_0 on the server. You must also
- put the *.BIO file on the disk with the ABIOS file and the CID
- server. Note that when you edit the ABIOS.SYS file and add the
- new .BIO filename to the list it must be in uppercase letters.
- This method may cause problems when installing on some types
- of machines and is not an official way to fix ABIOS problems.
