Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=119150 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 22 (0x16),(OS/2 BM: hidden DOS with 16-bit FAT (>= 32MB)) start 63, size 4096512 (2000 Meg), flag 0 beg: cyl 0/ head 1/ sector 1; end: cyl 254/ head 254/ sector 63 The data for partition 2 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 4096575, size 20964825 (10236 Meg), flag 80 (active) beg: cyl 255/ head 0/ sector 1; end: cyl 1023/ head 254/ sector 63 The data for partition 3 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 25061400, size 95040540 (46406 Meg), flag 80 (active) beg: cyl 1023/ head 255/ sector 63; end: cyl 1023/ head 254/ sector 63 The data for partition 4 is: <UNUSED> I'm not sure what we're looking for here. -- Regards, Doug _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
