Known Problems and Limitations

To use the AHA-3940 or AHA-3940W adapters, the motherboard must have a

BIOS that supports the DEC PCI-to-PCI Bridge chip on the host bus adapter.

User-level programs have exhibited problems on some PCI systems with an

Adaptec AHA-2940x card, including the following motherboard models:

PCI motherboards with a 60-MHz Pentium chip, with PCI chipset numbers

S82433LX Z852 and S82434LX Z850. The part numbers of the Intel

motherboards are AA616393-007 and AA615988-009.

PCI motherboards with a 90-MHz Pentium chip, with PCI chipset numbers

S82433NX Z895, S82434NX Z895, and S82434NX Z896. The part number of the

Intel motherboard is 541286-005. (Some Gateway 2000 systems use this

motherboard.)

The AA-619772-002 motherboard with 82433LX Z852 and 82434LX Z882 chips

causes random memory inconsistencies. Return the motherboard to the vendor

for a replacement.
