Known Problems and Limitations

Some motherboards have problems supporting channel B with boards based on

the Adaptec AIC-7895 chip, such as the AHA-2940U Dual, AHA-2940UW Dual,

and the AHA-3940 series. The problem arises because the BIOS doesn’t properly

assign two interrupts for PCI interrupts INTA and INTB on the slot containing the

AIC-7895 chip. This causes devices connected to channel B to fail, and messages

about timeouts and resets on those devices to appear on the console.

For example, this problem occurs on the Intel PR440FX (Providence) dual Pentium

Pro motherboard, with BIOS revisions up to and including 1.00.08.DI0. For that

motherboard, a workaround is to set the “Advanced/PCI IRQ Mapping” feature
