I originally was creating a new hard drive image. (Actually, I was just
copying one I already had, but same result.) Plus in other tests before I
did the original post, I sometimes unpartitioned and repartitioned,
reformatted, etc. A variety.
Later, when I did the retests with bochs vs qemu, it was getting late and I
was getting tired, so I just used an existing partitioned image and simply
reformatted it for each test. So the only thing that was being kept was the
partioning, which didn't seem to cause a problem with anything.
As for the floppy images, they are all raw, uncompressed images. Otherwise
the floppy wouldn't boot at all.
I did just run a couple new tests. With fresh, unpartitioned, unformated
disks.
I can now get Dell Dos 3.30 to install and boot from C:
Dos 3.20 still fails in both qemu and bochs.
Dos 4.01 behaves a little differently, depending on its mood. Sometimes
it'll fail during the boot floppy stage. Other times it'll fail when
booting from C, sometimes with Qemu giving a fatal error and sometimes not.
I may get yet more odd results if I used a seperate boot floppy (that
presumably works) instead of the install disks.
Some of these problems and inconsistancies may come down to:
1) Bugs in the original OS.
2) The OS not liking the newer hardware of Bochs & Qemu
3) The OS being customized for specific hardware, and doesnt like Bochs or
Qemu.
4) The OS being a bit more picky about the partitioning and formatting than
newer versions.
5) The OS being warez of unknowned origin.
I'm beginning to suspect that number 5 is a major factor...
