SYS2025 and SYS2027 errors during instal 8/12/94
File:OSINSY25.fax 4/20/94
==================================================================
SYS02025 AND SYS02027 ON NON IBM MACHINES WITH
AMI BIOS ON DISKETTE #1
==================================================================
DESCRIPTION OF SYMPTOMS:
During installation of OS/2 2.x on OEM (Other Equipment
Manufacturers) machines with AMI BIOS, the system will
display two SYS error messages 02025 and 02027 after
inserting Disk 1.
SUMMARY OF RESOLUTION:
1. Make sure disk 1 is not bad.
2. Check the AMI BIOS date and Keyboard Controller Chip
version. The date should be 5/9/91 and Controller Chip
version should be F.
3. Ensure that there is not a hardware problem with the
Floppy Controller or Floppy Drive.
DETAILS OF RESOLUTION:
1. Try booting with the Disks on another machine that is
already running OS/2 2.x.
2. Machine must have BIOS dated 5/9/91 and keyboard
controller chip version KF. The following information
will be seen by the user at (cold)boot time:
AMI BIOS and AMI BIOS Plus:
aaaa-bbbb-mmddyy-Kc
AMI Hi-Flex BIOS:
ee-ffff-bbbbbb-gggggggg-mmddyy-hhhhhhhh-c
If an IDE hard drive is in the system, "mmddyy" should
be 040990 or later. For other drives including MFM,
RLL, ESDI, or SCSI, "mmddyy" should be 092588 or
later. Controller chip version can be located on the
bottom of that same screen. Check the last digit in
the long stream of digits (the "c" above). The last
digit will probably be either be 8, B, D, or F. The
required level should be F for OS/2 v2.x.
Pressing the INS key during bootup should cause this
information to stay on the screen.
If they are not up to date call Washburn & Co. to order a
new version.
3. If the above two steps do not solve the problem have some
hardware diagnostics performed on the Floppy Controller
and Floppy Drive.
=============================================================
SYS 2025 & 2027 on the Install Disk of OS/2 2.1
=============================================================
Getting sys02025 and sys02027 on the install diskette.
If floppy drives were switched, make sure the CMOS was updated to
reflect the change. Setting CMOS correctly allows the install
without getting the sys02025 and sys02027.
Pg 2
This is different from OS/2 2.0 where it allowed you to install and
then asked for a nonexistent diskette 16 at the end.
=========================================================================
SYS02025 and SYS02027 on OEM with PHOENIX bios 1.03 on OS/2 2.1
Install Diskette.
========================================================================
DETAINS OF RESOLUTION:
1) Make backup copy of OS/2 2.1 Install diskette.
2) Del OS2LDR /* from backup diskette */
Del OS2BOOT /* from backup diskette */
3) Copy OS2LDR /* from original to backup */
Copy OS2BOOT /* from original to backup */
Note that there is a tool available on the NSC BBS and Compuserve
that allows you to install OS/2 2.X from the B drive, when the B
drive is 3.5 and and A drive is 5.25 and the diskettes are 3.5.
This utility is called INST21L (if you have blue labels on your
disks) or INST21M (if you have salmon label on your disks).
