I wanted to dedicate disk #2 to FreeBSD 2.1 (Disk #1 contained : MSDOS "Slice" 300 MB, a NETBSD slice and a free = slice, I don=B4t know the sizes of the netbsd and free slices). Now, in the dialog to create a partitions in slices, there=B4s not enough room to hold all i got with the "A"-command, so i decided to delete all partitions on sd0 (=3D=3DDisk #1). Unfortunatley this seems to wreck the disklabel on sd0 for the netbsd slice. Also it wrecked the MBR for sd0 since it seems to be problem with geometry translation. FreeBSD installed fine, but after rebooting when i was asked for what i want to = run (F?) only F5 for disk2, which is FreeBSD, worked. Using Norton Utilities is found that the MBR on disk #1 was messy (size = of partitions still ok, but Cylinder/Sector numbers for Start+End was wrong). I managed to get MSDOS working again. But no way to set up the Netbsd and free partitions correctly again (since i don=B4t know the size of them exactly). I found the disklabel of the (old) Netbsd slice = using Norton Utilities right after the end of the MSDOS partition. But i = don=B4t know enough to interpret whats in there. I=B4m pretty sure that the installtion only messed up this disklabel (does = it write any bootcode?), so, hopefully, the superblocks and filesystems = from netbsd are still ok. Actually i could live with getting the data = off the /usr and /home filesystems (Yes, i know i should have done a = backup). Does anybody have an idea to get it back ? Problem 2: Sometimes, like 3 out of 4, when i "halt" or "shutdown -h now" FreeBSD = 2.1 the systems hangs before or after printing "Rebooting". It makes it = always up to "syncing disks...". When this happens i must press reset to = reboot the computer, and i comes up with "CMOS checksum incorrect". So i do load the defaults and modify them as needed (new date/time etc.) The system then comes up fine and is running ok, til next shutdown or = halt. I=B4m stilling running the kernel that i got from the installation, may this be a problem ? Any ideas ? Since i don=B4t have access to news very often, would you please reply by email ? Email is : laubner@ctron.com = Thank you ! Cheers Guido
