IIRC 16k IBM PC could not boot DOS. You were pretty much stuck in ROM cassette BASIC.

- userbinator 7y agoYou're right: http://www.os2museum.com/wp/dos/dos-1-0-and-1-1/ http://www.os2museum.com/wp/dos/dos-1-0-and-1-1/ It should be noted that DOS would theoretically be able to run on the base PC model with 16KB RAM. However, this was not an option in practice: The PC’s BIOS loaded the boot sector (from a floppy) at address 7C00h, which is 31KB, meaning that it was not possible to boot DOS on a PC with less than 32KB memory.
- basementcat 7y agoYou got me wondering if an actual 16k IBM PC BIOS would load the boot sector into the rolled over address 0x3c00 instead of 0x7c00. Has anyone (recently) tried to actually boot PC-DOS 1.0 on an actual 16k machine?
