Installing on Computers with ABIOS 4/27/94 File:ABIOS.fax 4/15/94 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. 12/31/99
