Good afternoon and thank you all for existing! I'm a FreeBSD (and Unix) newbie, but excitedbie. I have the 2.0.5 Walnutcreek dist. and am trying to install on my new computer, but the kernel can't find my hard drive. Details: Cyrix 6x86 P150+ on an MTI board with Triton II chipset, 32M RAM Adaptec 2940W running Seagate 32550 2G hard drive Adaptec 1542 running Pioneer ... CD-ROM and Colorado 2G QIC tape drive. #9 771 video. 3Com Etherlink III PCI 10t/102 NIC

I've seen in a couple of readmes that 2.0.5 supports both the Adaptec 2949 and the 3Com card, but my initial attempt failed - probing ahc1 and zp0 both returned 0x0. There appears to be no ahc0 in my kernel. The 1542 responded. So, I have two questions: Do I need 2.1 Are there any problems with using these two SCSI cards?

You need 2.1 for the AHA2940.

The 3COM card needs a newer SNAP than that, I believe, since it's new hardware and they didn't use a compatible chipset. If you had a model number instead of "Etherlink III" (509 maybe?) someone (not me) could tell you if plain 2.1 would work, or if you really need the snap.

There is no problem usingmultiple cards.

The 1542 will need to have bounce buffers enabled. This should be automatic in 2.1 and above.
