By the way, the manual - Installing and Running FreeBSD - is in contradiction: at page 7 ahc0 is 294x, and ahc1 is 274x, while at page 165 ahc0 is 274x, and ahc1 is 2940/3940. And then again at page 181, 27dx is ahb0, while 174x is ahc0, and ahc1. At any rate, I learn more about this, as I go along. Some more information related to the PCI problem: I installed the Adaptec PIC-SCSI card into a Compaq DexPro 6200 XL, as a second SCSI adapter, I disabled the embeded SCSI (AMD), and the FreeBSD installation went well so far - I didn't boot yet. What I think is relevant is that 'boot -v' listed this time the following: pcibus_setup(1): mode1res=0x80000000c (0x80000000), mode2res = 0xff (0x0e) as opposed to when it failed: pcibus_setup(1): mode1res=0x80000000c (0x80000000), mode2res = 0x0c (0x0e) It seems that the value 0 of bit 1 causes the failure. 2. > > > Any plans to add support for the AMD SCSI adapter that is embedded with > > Compaq DexPro 6200 XL? > > Not that I am aware of. > Apparently the Compaq's PCI Ethernet (AMD) is recognized but no driver exists. So it looks like a further mismatch between Compaq and FreeBSD. Alex
