Message-ID: <1049@galileo.rtn.ca.boeing.com> Date: 10 Aug 92 14:43:15 GMT Organization: Boeing Commercial Airplane Group, Seattle Lines: 40 I have not been able to make 386BSD work on my system when I use a DOS type partition table to divide the disk. The drive is a Maxtor 7120AT IDE drive. 386BSD works fine when I give 386BSD the whole disk. When I use a DOS partition table, I can run install which labels and sets up the 386BSD partition and copies a bunch of files to the disk. If I use ^C to interupt install just instead of allowing it to reboot, I can mount and access the 386BSD partition as wd0a. However, once I shutdown, I can no longer access the 386BSD partition. When I boot on it, the system seems to report all the devices, complains that it can't mount the root volume and reboots before I can decipher all the runes. (I made sure that the 386BSD partition started on a cylinder boundary). When I run the disklabel program it complains that it can't find the disklabel on wd0. If I create a disklabel for wd0, the DOS partition table is overwritten (disklabel tells me that it is doing this). I have checked that MSDOS, the CMOS and disklabel are all in agreement concerning the geometry of the disk itself. This data also matches the data reported by the drive via the IDEINFO program. It appears that the 386BSD can not properly use the MSDOS partition table to locate the 386BSD partition. Any help on how to fix this would be greatly appreciated.
