Surprised heck out of me, I figured anything that happened before FreeBSD could even boot couldn't possibly be FreeBSD's fault. da0 is the old 4G, da3 is the new one: ROOT:/usr/src:106 >fdisk -s /dev/da0 /dev/da0: 525 cyl 256 hd 63 sec Part Start Size Type Flags 1: 63 8467137 0xa5 0x80 ROOT:/usr/src:103 >fdisk -s /dev/da3 /dev/da3: 2231 cyl 255 hd 63 sec Part Start Size Type Flags 1: 63 35840952 0xa5 0x80 It doesn't look like that's the problem, but it was probably worth posting just in case someone else was scratching their head over it. Besides, if I move da3 to be on the DK440LX's 7895 (ch A, like da0) and have it replace da0, it boots on the 7895 just fine, it just won't boot on the 29160. I've been wondering if there's some sort of upper limit of the number of disks that the system can see (I have 2 on 7895 ch A and 3 on 7895 ch B) so the 29160 starts off as the 6th disk. The BIOS is very intelligent, it recognizes the 29160 and allows me to set the drive 0 on the 29160 as the boot drive, but when I do that, it just hangs, no boot. ---------------------------------------------------------------------------- Chuck Robey | Interests include C & Java programming, FreeBSD, chuckr@picnic.chuckr.org| electronics, communications, and signal processing.
