Mounting DOS HDD image

Mounting dos hdd image, first partition:

mount -o loop,offset=32256 dos-hdd.img dir

I’m using such image to update BIOSes in machines where bios doesn’t fit into floppy image. Such hdd image can be places inside iso image to be booted at virtual or real cdrom.

mkisofs -v -r -T -J –hard-disk-boot -b dos-hdd.img -o ../test.iso .
