Before Installing Os/ 2 Warp - IBM ThinkPad 760E Instruction Manual

Before Installing OS/ 2 Warp

760
ESS
Important
If your computer is the 760EL (ESS AudioDrive model), you
must do the procedure described in this section before you
install OS/ 2 Warp. Otherwise, the OS/ 2 installation stops and
you cannot complete the installation.
During the installation of OS/ 2 Warp using the OS/ 2 Warp Diskette 1,
the installation stops at the OS/ 2 logo screen and does not move
beyond the screen. This is because the ESS AudioDrive feature in
the computer uses the I/ O address 330h (for the MIDI port), where a
Sony ** CD-ROM device driver in the OS/ 2 Warp Diskette 1 accesses
to detect if the following CD-ROM drive is attached to the computer:
Sony CDU-31A, CDU-7305, CDU-33A, or CDU-7405
To avoid the installation stop, do one of the following, depending on
your situation:
If you are using one of these Sony CD-ROM drives,
refer to the chapter describing the special hardware
considerations in "Special Hardware Considerations" in the
User's Guide to OS/ 2 Warp and read the parameter information
for the SONY31A.ADD device driver.
After that, you might need to disable the ESS audio, or change
the ESS audio system resource to avoid any resource conflicts.
In that case, start the ThinkPad Features program and register
the Sony CD-ROM's resource information. Then set the
appropriate resources for the ESS audio in the ThinkPad
Features program.
If you are not using these Sony CD-ROM drives, do the
following:
1
Make a backup copy diskette of the OS/ 2 Warp Diskette 1.
2
Open the CONFIG.SYS file in the backup copy diskette
using your editor, and comment out the Sony device driver
line as follows:
rem BASEDEV=SONY31A.ADD
