Comment: I have a 40 GB disk with this partitioning scheme: Three primary partitions and one extended 1. 4GB Windows 2000 (NTFS) 2. 3GB Win 98 SE (FAT32) 3. 1G DOS 6.22 + Win 311 (FAT16) Extended partition contains 4. 6GB Win XP (NTFS) 5. 20GB FAT32 for data 6. rest linux (EXT2) I have read and verified that DOS's boot sector cannot boot IO.SYS etc if the dos partition starts above the first 2GB of the disk. However, if I boot from floppy my dos partition is visible because it is still below the 1024 cylinder limit (below 8 GB). I use Win 2000 boot loader (boot.ini). I have put the boot sectors of the OSs in a seperate file but dos cannot boot with this configuration. I don't want to put dos first bacause it will always be in drive C: Where can I find an updated boot sector which can boot dos if it's partition is above 2GB? Or how can I patch the boot sector to do it?

Reply: (edit)For example, split your 40GB HD into two 20GB FAT32 partitions: C: FAT32, 20GB D: FAT32, 20GB Then install MS-DOS 7.10 or similar (e.g. FreeDOS Kernel 2032). Then DOS will see and access all data on your HD!
