INSTALLING AST 3G PRODUCTS WITH OS/2 EXTENDED EDITION
|
|
|
|
|
|
To insure compatibility with AST OS/2 Extended Edition 1.10, the AST 3G Plus
|
|
(part number 202104-XXX) must have BIOS revision level "F" or above
|
|
installed. The BIOS chip is located at U29. The revision level can be read
|
|
directly from the label on the BIOS chip.
|
|
|
|
Likewise, the AST 3G Plus II adapter (part number 202161-XXX) must have BIOS
|
|
revision "D" or above installed. The BIOS chip on the 3G Plus II is located
|
|
at U10.
|
|
|
|
In addition, Hercules emulation must be disabled for both of the above video
|
|
adapters when used with OS/2 Extended Edition. Hercules emulation generates
|
|
non-maskable interrupts which conflict with OS/2 initialization. Consult the
|
|
respective 3G adapter User's manual for the method of disabling Hercules
|
|
emulation.
