Hi, I've spent a few hours over the last couple of days hacking the aic7xxx driver (V5.0.19) in kernel version 2.1.107 to detect and support an Adaptec 2940U2W (Ultra2 LVD controller). I have *NO* idea if I am on the right track or not. Currently I'm just working through the FreeBSD cam code (from ftp://ftp.freebsd.org/pub/FreeBSD/cam/) and adding things which aren't apparent or seem Ultra2 specific into the aic7xxx driver. At the moment, the 2940U2W card is detected through pci, and then the card is reset. However, while scanning the scsi bus, it continually times out and attempts to query id 0. The controller has an LVD hard disk at scsi id 6, narrow ultra cd roms are at 3 and 5. At the moment, I'm really only interested in getting the cdroms going (bread and butter). The hard disk can wait. From the comments in the freebsd cam code it seems that LVD harddrives haven't been checked/verified yet, so I'm not too worried. Does anyone feel like lending a hand? I'm in the middle of exam marking (*sigh*) and am only using this as a distraction infrequently. If there is any interest I'll make a snap shot of the patches to the above kernel/driver version and put them up on the WWW. -Greg ------------------------------------------------------------------ Lecturer Dr. Greg Wickham School of Computing and Mathematics ______________________________ Deakin University Voice: (+61 3) 5227 1381 Geelong VIC 3217 eMail: G.Wickham@deakin.edu.au Australia WWW: http://www.cm.deakin.edu.au/~gjw ------------------------------------------------------------------ wheNufiNdu'RselFindAngeRwheNu'rThreAtenEdbyAstrAngeRwheNitlOoksLik To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
