I have seen similar symptoms, where an error early in the boot
sequence, in this case from your scsi card as it struggles with your
powered down scanners, will prevent a range subsequent initialisations
from taking place. Hence the loss of your IP stack and the loss of the
updated scsi drivers.
I am not unfamiliar with your specific scsi card, but in general
devices are allowed to be powered down and the scsi bus should still
work. This looks like a termination issue. You need to ensure that
there is a terminator on the last device and that the computer is
providing term power to it.
My guess is that this is not the case, and the one or other device is
preventing the bus from working while its off.
You may be able to determine which device it is by removing them one at
a time.
Relying on internal terminators on a scanner may be the problem.
Turning off any internal termination and fitting proper external
termination may help.
We have not dissimilar grief with a Canon 5p scanner that is connected
to both the RISC PC and the windows box. In this case the Acorn is
fine, but the PC takes ages to boot if the Acorn is off. (We set the
scsi id of the PC Adaptec card to 6, the scanner to 0 and the acorn is
7)
