- If you format you drive with fdformat a special bootsector is loaded.
- The bootsector looks if the disk is bootable
- - yes - load io.sys msdos.sys command.com etc...
- - no - load bootsector of harddisk
-
- You can use debug to debug the boot sector of the disk in A:
- (or a disassembler)
- when you replace mov xx,80 (hex) with mov xx,1 (b:) then the B: gets
- booted. I tried it (a year ago) and it boots....
-
- BUT I tried to boot ms-dos, and ms-dos doesn't like to be booted from
- B: and gives problems.
-
- If you want to play old games from 5.25" you can change some connectors
- of your floppy drives (let a good person do that) and make
- A:--> B: and B:--> A:
