ISA AT BUS Installation workarounds (CP) 4/29/94
File:OS2ATBUS.FAX
TITLE:AT BUS WORKAROUND FOR INSTALL
ISA BUS WORKAROUND FOR INSTALLATION PROBLEMS
ON AT (ISA) BUS MACHINES
----------------------------------------------------------------
CONFIGURATION: AT-bus (ISA) machine
non-SCSI disk controller (RLL, MFM, ESDI)
sometimes occurs on IDE controllers
SYMPTOMS: Very slow install
Very noisy hard disk during install
FDISK errors
Very slow operation
**For OEM systems, it is recommended to disable the following:
Turbo, Cache, and Shadow Ram
(Packerd Bell system need not disable these feature)
**While installing ALL systems should disconnect devices such as:
Modem, tape backup, Network card, scanner, etc.
**After installation completes ENABLE all feature and reconnect
any devices you disconnected.
WORKAROUND BEFORE INSTALLATION:
----------------------------------------------------------------
Step 1: Make a DISKCOPY of Diskette 1. Use DOS to edit the
CONFIG.SYS on Diskette 1 copy.
NOTE: Diskette 1 is the first diskette AFTER the Install Disk.
Change the line: BASEDEV=IBM1S506.ADD
To read: REM BASEDEV=IBM1S506.ADD
This will use the IBMINT13.I13 driver. After install
completes, it is recommended to un-REM the driver.
Alternate to Step 1 Above:
----------------------------------------------------------------
If you don't have access to DOS OR do not have a DOS editor to
edit the CONFIG.SYS, as an alternate to editing the CONFIG.SYS
file on Diskette 1, you may follow these steps:
a) Insert the Installation Diskette into drive A
b) Turn on the computer. If the computer is already on,
press and hold Ctrl+Alt and press Del to restart system.
c) When you are prompted to do so, remove the Installation
Diskette and insert Diskette 1.
d) Press Enter.
Pg 2
e) When the Welcome screen is displayed, press Esc to display
the OS/2 command prompt.
f) With Diskette 1 in the drive, rename the IBM1S506.ADD to
IBM1S506.OLD by typing the following at the prompt:
RENAME IBM1S506.ADD IBM1S506.OLD
g) Continue with Step 2.
Step 2: Insert the Installation Diskette into drive A.
Step 3: Turn on the computer. If the computer is already on,
press and hold Ctrl+Alt, and press Del to restart the
system. Proceed with Diskette 1 through 5.
Step 4: After Diskette 1 through 5 are processed, you
will be asked to reinsert the Installation diskette.
DO SO.
After copying some files from the Installation diskette,
you will be asked to remove the Installation diskette
and press Enter to reboot. DO NOT DO THIS. LEAVE THE
INSTALLATION DISKETTE IN THE DRIVE.
*NOTE: In OS/2 2.1 the installation is slightly
different, it will ask for the installation diskette
then diskette #1 at this point you will see the message
take out the diskette and reboot DO NOT DO THAT, INSTEAD
PUT THE INSTALLATION DISKETTE BACK IN THE A: DRIVE.
Step 5: Press and hold Ctrl+Alt and press Del to restart the
system.
Step 6: Your computer should now be rebooting off the
Installation Diskette.
Step 7: When you are prompted to do so, remove the
Installation Diskette and insert Diskette 1.
Step 8: Press Enter.
Step 9: When the Welcome screen is displayed, press Esc to
display the OS/2 command prompt.
Step 10: You are now at a command line. If you are NOT
attempting to install HPFS, continue on to the next
step, otherwise execute the following steps to load the
HPFS driver.
Insert Diskette #2 in the drive, and enter the following
command:
CHKDSK c:
(If your operating system will reside on a drive other
than C, use the appropriate drive letter instead.)
Pg 3
Step 11: Enter the following commands:
RENAME C:\OS2\IBM1S506.ADD IBM1S506.XXX
COPY C:\OS2\IBMINT13.I13 C:\OS2\IBM1S506.ADD
(If your operating system will reside on a drive other
than C, use the appropriate drive letter instead.)
Step 12: Remove the diskette from the drive. Press
ALT-CTRL-DEL to reboot the system, and install should
pick up where it left off.
WORKAROUND AFTER INSTALLATION:
-----------------------------
Open the system folder on the desktop, then open Command Prompts
Folder Open OS/2 Window, at the prompt go the OS2 subdirectory on
the drive that OS2 was installed on, and type:
RENAME IBM1S506.ADD IBM1S506.XXX
COPY IBMINT13.I13 IBM1S506.ADD
Close all open folders and proceed with a proper shutdown. When
the machine is rebooted the change will take effect.
