Before you blame your problems on Linux or Grub you should know that there are no universal standards governing the way partitions are defined and managed. Different operating systems have different ways of doing it. I can't remember where I read it, but a valuable bit of advice is to use _only_ the partition tools provided with your operating system.

I guess it is MY fault for having the temerity to try running a multi-partition DOS HD slaved to a Linux-booted HD. The only thing GRUB is doing is telling the BIOS that the slave is the master, so boot it from its MBR. This does not explain why the partitions are duplicated. -- Leon A.

Cause DOS is too stupid to know how to interpet the partition table correctly? Could be, but the question is - how does smart DOS, that boots perfectly as a master, suddenly become stupid when it is slaved? I can expect weird things with DOS sharing a hard drive with other OS's, but this is a separate drive, with DOS bootloader in its MBR. It's only association to the master is the menu.lst. There are no FAT partitions on the other drive to confuse it. -- Leon A. Goldstein Powered by Libranet 2.7 Debian Linux System 5WV271

Leon A. Goldstein wrote: (I posted this enquiry on the Caldera mail list but got no response. My apologies if any list member has seen this already.) I want to slave a DOS/Win3.1 HD to one of my Linux boxes. I can boot the DOS HD using GRUB: (menu.lst) TitleDR-DOS map (hd1)(hd0) rootnoverify (hd1,0) makeactive chainloader +1 boot This works, although the recipe is not exactly as prescribed by the GRUB documentaion I read. I'm supposed to have a second map entry: (map (hd0)(hd1)) but that simply does not work. The above menu.lst works with WS.3.1 and Libranet 2.7. With DOS so booted, the problem is that my partitions are skewed. I have a 1.6 GB HD partitioned with one primary and three logical partitions. When I run PCTools (remember that great utility?) the partitions are listed as C,D,E,F,G,H,I,J Examination reveals that C is duplicated in D, the real D is E and duplicated in H, and so on. I can run all apps in the C partition, but Windows is knocked out because it is in another partition and the mapping screws up the paths. Any suggestions? If I can solve this, I want to donate my original DOS box (with a new HD) to a local no-kill animal shelter. -- Leon A.
