- ISA BUS WORKAROUND FOR INSTALLATION PROBLEMS ON AT (ISA) BUS MACHINES
- ---------------------------------------------------------------------
-
- CONFIGURATION: AT-bus (ISA) machine.
- Non-SCSI disk controllers (RLL, MFM, ESDI).
- Occurs on some IDE configurations as well.
-
- SYMPTOMS: Very slow install
- Very noisy hard disk during install
- FDISK errors
- Very slow operation
-
- There is a modified version of the device driver IBM1S506.ADD that is
- available. This driver fixes the symptoms described above. If you are unable
- to obtain the new driver, the workaround described below will alternatively
- allow you to install and use OS/2 2.0, however, it is recommended that you
- obtain the driver, since the IBM1S506 driver offers better performance than the
- generic IBMINT13 driver.
-
- WORKAROUND BEFORE INSTALLATION:
- ------------------------------
- Step 1: Use DOS to edit the CONFIG.SYS on Diskette 1 in the 2.0 package.
- NOTE: Diskette 1 is the first diskette AFTER the Install diskette.
-
- Change the line -
-
- BASEDEV=IBM1S506.ADD
- to
- REM BASEDEV=IBM1S506.ADD
-
- 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 the system.
- c) When you are prompted to do so, remove the Installation
- Diskette and insert Diskette 1.
- d) Press Enter.
- 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+Del to restart the system. Proceed with
- Diskette 1 through 5.
-
- Step 4: After Diskette 1 through 5 are processed, you will be prompted to
- reinsert the Installation diskette.
-
- 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.
-
- 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 to OS/2 gray screen is displayed, press Esc to
- obtain an 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.)
-
- 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,
- us 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.
