I'm building a DOS PC (or two, or three!!), today the last of the parts I needed arrived so tonight I finally got to start playing, only I can't even install DOS! The CF card is detected in BIOS, I can boot from floppy, run the DOS setup and let it prepare the "hard disk", then it restarts, gets as far as asking where I want to install (C:\DOS), then gives an error about not being able to access C:\DOS, upon exiting setup I can see it's tried to create a folder called "DOS" but instead has created a folder called "DNS".
I've tried "format c: /s", which appears to work, i.e. no errors, but instead of command.com I get cnmland.cnm, obviously something's not right!
I have a USB CF card reader, but after formatting the CF card in DOS it's not readable from my windows 10 PC, it says I need to format it to use it, if I format the CF card in windows 10 (FAT) it won't work in DOS, using fdisk it shows as a non-dos partition.
I've tried 2 different CF cards, one is an old 512mb card the other is a new 32GB card, the old card takes a while to format in DOS, much like an actual hard drive, the new card is really fast, but both have the same result.
I've also tried 2 different motherboards, 2 different processors and a selection of RAM modules, as well as the MS DOS 6.22 setup disk and an MS DOS boot disk, always the same result. If I use "copy a:\*.* c:\*.*" after "format c: /s" all filenames are correct but it still won't boot, it seems to be detected as a bootable drive but doesn't actually boot.
Could this be a problem with the IDE to CF adapter? There doesn't seem to be much going on on the adapter that could cause a problem, I have another couple of adapters coming from China (bought one from UK to get me started and 2 from China for the other 2 potential builds), I wasn't expecting problems this early in the build!
