I tried all options i can think of, but it always failed: boot0 and boot1 work nicely, but boot2 simply hangs as soon as it tries to do the first bios read from the array. I am somewhat suspecting that this is related to the BIOS of that controller being of low quality. That and/or some bug in boot2 related to it being a btx client and fiddling around with the protections and thus giving the raid controllers' bios too hard a time. - Tried FreeBSD 5.0(release) and 4.8(release) boot1/boot2 - same effect. - Problem is unrelated to disk being a raid. Same effect happens when simply moving a perfectly booting ide disk from a "normal" ide controller to the sx6000 (hangs in boot2). - Windows XP boots fine off the sx6000 (also via FreeBSD boot0). Have not tried other OSs like Linux though. - Tried all "OS" settings in the sx6000 BIOS config. No change. - Q: Any ideas what i could do ? - Q: Is btx actually switching to real mode for int 13 ? Could it be that there's a bug in that code ? - Q: Are there any alternatives how i could boot a 4.8 or 5.0 freebsd solely from the disk ? (I guess i could try to install a linux and then use liloboot, but that also uses the btx code from loader...) Thanks Toerless
