I have been using the IBM5160 PC driver in MAME for booter games and it works fine. However, now I'm trying to plug a HDD on it with MS-DOS 6.22 instaled on it but the system refuses to boot through the HDD. It prints "missing operating system" on screen and that's it. I'm using a 20MB HDD I created for my AT486 driver, which works fine with that driver.
I also tried to boot the machine using a MS-DOS 3.3 double sided 5,25" floppy disk image but it says that the operating system was not found and ask me to insert the system disk and press any key. But I know that the disk is configured properly, I tested it through the AT486 driver and it boots fine there.
What am I doing wrong?
