AST PREMIUM SYSTEMS WITH BUILT-IN MOUSE PORTS AND ADIC'S DCB
|
|
|
|
|
|
When installing two ADIC DCB controller cards, Channel 1 and Channel 2 in an
|
|
AST computer, errors will occur on the second DCB controller which is Channel
|
|
2, (i.e., Channel 2 will fail to initialize under Novell Netware environment
|
|
and will also fail ADIC diagnostics).
|
|
|
|
The problem lies with IRQ12, which supports the PS/2 mouse port. ADIC's DCB
|
|
controller card Channel 2 is hard wired, this cannot be changed. (IRQ12 is
|
|
accepted as Industry Standard for PS/2 mouse port). ADIC's Technical Support
|
|
recommends that the customer using the DCB Channel 2, switch and use DCB
|
|
controller Channel 3 which uses IRQ10. Customers experiencing the above
|
|
problem should contact ADIC's Technical Support to exchange DCB controller
|
|
cards.
