Well, if you want to see the code that's complaining about "cylinder 1024", see "/usr/src/sys/i386/boot/biosboot/disk.c", function "Bread()" (line 218 in 2.2-snap-960801). The variable "spc" is the number of sectors per cylinder (= sectors-per-track * number-of-heads, using BIOS geometry). Given the small size of your root partition, I can't think of many possibilities: either a block number is pointing off into deep space (shouldn't fsck catch this?), or your BIOS geometry is really weird. -- Darryl Okahata Internet: darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
