This is why we only negotiate at 10MHz. Strangely enough, I have a similar motherboard (Intel, dual P6-200 Natoma, with onboard 7880) where the BIOS does set the ultra enable bits as expected. Are you sure that the SCSI-Select settings in your BIOS are set for ultra for these devices? It could be that I "fixed" a bug in the setup code of the driver that masked this problem for you in the past. I spent a bit of time this morning going over the code and it looks correct. If your BIOS is setup correctly, I'll have to whip up some patches to make the adapter setup more verbose. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
