After doing the sysinstall thing, it wouldn't boot off the hard disk; I had to boot off the floppy and do: disklabel -B -b /usr/mdec/boot1 /dev/rda0 That was the only step that sysinstall was missing. My guess is that, if you are testing sysinstall on your own machine, you probably already have the correct boot block on the disk and so not noticing the failure of the install process to set it up. You might want to try: dd if=/dev/zero of=/dev/rda0 bs=1m count=1 to wipe the disk between install attempts. On x86 I keep a standalone boot floppy with an MFS root handy for just this operation. >Also, just curious: Is the kern.flp working correctly now in that it >prompts for and correctly loads the mfsroot, then boots?

FreeBSD's view of the >disk is determined solely by libdisk, so if it's out of sync with the >kernel's own partition search order, that's something to look into. Um, I'm not even sure if NetBSD/alpha uses PC style partitioning at all, or just writes a BSD disk label. I'd assume it just writes a BSD disk label, so the 0xA9 stuff you mentioned would be irrelevant. The disk is wiped now, so there is no easy way to go back and see what NetBSD was doing with it. In any case, it is definitely true that the FreeBSD kernel's view of the disk is different from libdisk's. Witness the fact that the FreeBSD kernel, when booted off the floppy, found and used the NetBSD root file system and was able to run in single user mode, but sysinstall didn't see those partitions at all. >Hmmm.

How about a nice cyan or something? :-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
