Hi there,
I had machine with Linux in the first PATA disk (wd0) and OpenBSD v4.1 in the second PATA disk (wd1). OpenBSD was booted from Grub menu (hd1,3). I added 3rd harddisk to my machine by connecting it into Promise SATA378 controller. The Linux boots normally and the new disk is visible as /dev/sd0. The OpenBSD kernel boots but re-enumerates disks differently showing lines like (I skipped some): " dkcsum: wd0 matches BIOS drive 0x82 dkcsum: wd1 matches BIOS drive 0x80 dkcsum: wd2 matches BIOS drive 0x81 Can't open /dev/rwd1a: Device not configured Enter pathname of shell or RETURN for sh: " How should I proceed? Should I remove the SATA disk => manually change wd1s to wd2s in my /etc/fstab => put SATA back => reboot. Or can I fix enumeration from the proposed Shell -prompt only. -pekka-
