Subj : Partition Tables To : comp.programming From : Bill Cunningham Date : Wed Aug 17 2005 06:01 pm I assume the partition table is stored with other information in the MBR. Could I write a small program in C or assembly that would look at the bytes in the MBR to find the partion's signature. I have win98 in a FAT32 partition but I want MSDOS 6.21 to reside in a partition next to it. I don't know what the native partition is for MSDOS. It must be a 16 bit filsystem. If I install MSDOS 6.21 using setup it rewrites the MBR and I have a 16 bit file system with all the info I had before lost. Bill .
