First, apologies to any subscribers to FeeeBSD-hackers, who may have already seen a very similar question, which I posted there last week. However, judging by the content of that list, I guess that this FreeBSD-questions list may be a more appropriate forum. Can anyone advise me if my system is repairable ? I was running FreeBSD 2.2.5 and W95 happily on my machine. wd0 contained W95, and wd1 contained FreeBSD Suddenly while running W95, everything went "pop" and I wasn't able to boot either. So, booting from floppy, using the "fixit" option, and running fdisk I get the following :- fdisk wd0 *** working on device /dev/rwd0 *** parameters extracted from in-core disklabel are: cylinders=4095 heads=16 sectors/track=63 1008 blks/cyl) Figure below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=4095 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information for partition 1 is: <UNUSED> Information for partition 2 is: <UNUSED> Information for partition 3 is: <UNUSED> Information for partition 4 is: <UNUSED> fdisk wd1 *** working on device /dev/rwd1 *** parameters extracted from in-core disklabel are: cylinders=4095 heads=16 sectors/track=63 1008 blks/cyl) Figure below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=4095 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information for partition 1 is: sysid 128, (Minix 1.1 ....... 1.4a) start -61531, size 63 (0 Meg), flag 0 beg: cyl 0/ sector 0/ head0; end: cyl 0/ sector 1/ head1; Information for partition 2 is: sysid 0,(unused) start 0, size 0 (0 Meg), flag d1 beg: cyl 0/ sector 62/ head 251; end: cyl 0/ sector 0/ head 0 Information for partition 3 is: <UNUSED> Information for partition 4 is: sysid 165, (FreeBSD/NetBSD/386BSD) start 1, size 4127759 (2015 Meg), flag 80 beg: cyl 0/ sector 2/ head 0; end: cyl 1022/ sector 63/ head 15 My understanding of the above is limited, but I get the impression that my W95 (wd0) installation is gone, but my FreeBSD is still there in slice 4 of wd1. Based on the above information, can anyone confirm that my FreeBSD installation is still there, and that the challenge is how to boot it. I wrote a boot manager to the first disk (wd0), and now when I boot I get the following F5 .... disk 2 Default: F5 F5 .... disk 2 Default: F? Alternatively, would anyone like to suggest that the system is lost, and a fresh installation is required. Any advice on how to proceed, or where appropriate documentation may be found would be appreciated.
