Hi all,

pre 15 works for me without problems on an Asus P2B-LS. There is still a
question left i asked some mails ago. If i take a look into
/proc/scsi/aic7xxx/0, i see

Statistics:
(scsi0:0:0:0)
Device using Wide/Async transfers.
                         ^ ^ ^ ^
Device Negotiation Settings
Period Offset Bus Width
User       000    000        1
Goal       000    000        1
Current    000    000        1
Total transfers 3595 (3370 read;225 written)
blks(512) rd=16267; blks(512) wr=654

This should be definitely synchronous, because the harddisk is an IBM
DGHS09V Ultra2-SCSI, which of course is capable of ultra2 synchronous
transfers.

So, what is the REAL transfer mode? 80 Mbyte/s synchronous or 20 MByte/s
or
less asynchronous?

Greetings
Michael
