terror with adaptec aha1510b :-(
Hi all!
I have Matsonic MS6260S board with a k6-2 300, 64megs of ram, an adaptec aha1510b
isa scsi controller, a micropolis 9GB (3391av) hd (active terminated), an ibm
dcas 3GB and an epson gt5000 scsi scanner connected via 1 meter hd50->centronics
cable + active terminator on the scanners sub-d 25 port. i set the controllers
termination to auto and this seems to work fine. since i installed the
controller i was not able to make the driver use a dma channel for it. i think
this is the reason why i get no more than 750KB/s from the harddrive, but it
worked without problems (except the speed) before installing the scanner.
now, when i want to scan sth (with xsane), preview functions properly, but when
i wanted to do the full scan, it does the half and then xsane locked up. one min
later the whole system hung and did not react anymore to any events (keyboard,
mouse, net) but the resetbutton :-(
but whats the reason? could it be related to the dma problem, or having sth to
do with parity? i think termination is fine, cause if i enable controller-
termination, the scanner is not found anymore, but when controller termination
is set to auto, its found.
i tested the scanner on another computer with exactly the same configuration
(hw&sw, except of the motherboard (asus p5ab), scsi-controller (Advance aha2941uw),
and the external scsi-cable), and it worked fine under LinuX and windoze98/nt.
any ideas?
TIA Stefan Bunse
