Hi, I removed the C000:8 and "| " strings and did this: xxd -r dump.txt | ndisasm - | less At first glance the analyzed payload of this "HighPoint IDE 386" thing looks like something which hooks int 13h (BIOS disk services) and hides the first 2 sectors on the disk from the user, both in CHS and LBA mode. I think the first 2 sectors will contain some kind of driver which you will only be able to see if you do not boot that HighPoint thing - or if you disable it later. Or if you use FreeDOS UDMA driver :-).
Actually the latter is dangerous! Loading the driver makes the drive contents "jump" back to their original position, which can be very confusing for all software which accesses the drive.
