Weird stuff here as well, not figure it out yet.
My oldest computer is a Multitech MPF-PC, 8088 IBM PC clone. It's got onboard fdd controller and a 360fdd attached, and an 8 bit ISA mfm controller with (if I remember the type correctly) 10MB Shugart SA712 hard disk attached.
Trying to boot from floppy drive with ms/pc DOS version 2.11, 3.1, 3.3, 5.02, 6.22 results in an error: DIOS.SYS not found.
Can press any key and the computer tries to boot again with the same error.
Trying to boot from floppy with cp/m results in booting, but a halt on I/o conflict.
Ctrl alt del will reboot as expected, but that's my only option from there. Need to fiddle with some motherboard switches I guess.
Prepared the hard disk with PC DOS 5.02 in another machine (ofc with its own controller), and the system will boot to DOS and command prompt... But does no longer respond to the keyboard.
Eventually I placed a head park command in autoexec.bat to secure the drive when I have to turn it off. Something I have to get onto some day.
Stuck at 10MHz...
