STATUS: BBS:YES
SYMPTOM:
The 9585 system displays a I9990303 System Partition
Boot Failure error message with OS/2 2.1 installed.
PROBLEM ISOLATION AIDS:
OS/2 2.1 was installed without using the Model 9585 setup
utility to copy the ABIOS files onto a newly created Model
9585 OS/2 2 install diskette.
A System Partition Boot Failure error (I9990303) occurs
the first time the System Partition is accessed.
Some time may have lapsed between the installation of OS/2 2.1
and the actual need to utilize the System Partition.
FIX:
1. BACKUP THE SYSTEMS HARDFILE (ALL DATA)
2. CREATE A MODEL 85 OS/2 2.1 INSTALLATION DISKETTE BY:
a. USING ANOTHER MACHINE, CREATE A BACKUP COPY OF THE OS/2
2.1 INSTALLATION DISKETTE. LABEL THIS DISKETTE AS THE
MODEL 9585 OS/2 2.1 INSTALLATION DISKETTE.
b. USING THE MODEL 9585 REFERENCE DISKETTE
1) COPY THE ABIOS.SYS FILE FROM THE
REFERENCE DISKETTE TO THE INSTALLATION
DISKETTE (CREATED IN STEP 2-A.)
2) COPY ALL *.BIO FILES FROM THE REFERENCE
DISKETTE TO THE INSTALLATION DISKETTE
(CREATED IN STEP 2-A.)
Note:
When encountering an I9990303 error on a Server 85 and
copying the ABIOS.SYS and *.BIO files as identified above,
be aware that there are two models of the 9585. Each model
uses a unique reference diskette as identified below. Failure
to use the correct diskette may result in TRAP 0002 or time
out errors during the subsequent installation of OS/2.
- If you are installing OS/2 on a 9585-0Xx, use the ABIOS.SYS
and the *.BIO from the 1.11 reference diskette.
- If you are installing OS/2 on a 9585-0Kx or 9585-0Nx, use
the ABIOS.SYS and the *.BIO from the 1.32 reference
diskette.
Note: If insufficient room exists on the backup copy of
the Installation Diskette for the new *.BIO files
you may delete the existing (old) *.BIO files from
the backup Installation Diskette.
c. INSTALL OS/2 2.1 USING THE NEWLY CREATED INSTALLATION
DISKETTE. (THIS DISKETTE SHOULD ONLY BE USED ON THIS
SYSTEM SINCE SOME OF THE ABIOS FILES ARE SYSTEM UNIQUE.
****************************************************************
WARNING: MAKE SURE THAT ALL DATA FILES HAVE BEEN BACKED UP
BEFORE PERFORMING A LOW LEVEL FORMAT. ALL DATA ON THE
HARD FILE WILL BE LOST.
****************************************************************
3. PERFORM A LOW LEVEL FORMAT.
4. INSTALL A SYSTEM PARTITION USING "RESTORE SYSTEM PARTITION"
FROM THE REFERENCE DISKETTE.
5. INSTALL OS/2 2.1 USING THE UNIQUE INSTALLATION DISKETTE
CREATED IN STEP 2 ABOVE.
6. RESTORE THE BACKED UP DATA FILES.
TECHNICAL EXPLANATION OF PROBLEM:
The OS/2 2.1 installation procedure invokes a sequence
of code paths that will calculate the hardfile space available
to the user for partition(s); C drive, or C and D drives, etc.
The ABIOS files are used if available. Otherwise, the OS/2 FDISK
code invokes a device driver that miscalculates the hardfile
space by one cylinder larger than it really is.
The 9585 system has a RAM loaded ABIOS architecture (FLASH) so
the files are not available during the initial installation of
OS/2 and the FDISK drive code path is invoked. This causes OS/2
to create a user partition (eg. C drive) which overlaps the part
of the hardfile containing the System Partition. When the user
attempts to access the System Partition the POST code does not
know if the System Partition is valid since OS/2 is claiming
this space. The System Partition is then marked invalid and
the I9990303 error is generated.
