TYAN K8WE (a.k.a. 2895) + Adaptec ASC29320A SCSI Controller

Is available:
Motherboard TYAN K8WE (a.k.a. 2895), SCSI controller on chip AIC7901
- it is connected in 133MHz/64bit PCI a socket, one disk is connected
to it
- MAXTOR ATLAS15K2_73SCA Rev: JNZ3 (73Gb/15000rpm)

At loading, and the beginning of initialization SCSI of a subsystem,

after check of all devices connected to the controller,
with probability 9/10 there is a mistake like this:
