============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0682 05-06-91 ============================================================================= 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.
