I've been trying to install various old versions of DOS under Window's v0.70 of qemu from FreeOSZoo.
And since so few people appear to be using the Windows version, I've been making a point to do as much testing as I can, with as wide a variety of operating systems as I can find. >From version 5 on up, I only have a few problems (Which I've already reported.) However, I got hold of some warez copies of Dos 3.30 (several copies) and Dos 4.01. They don't install. Running the floppies themselves usually works. But actually installing them or running off the hard drive causes problems. Using the command line (as created by qGui): h:\qemu\qemu\qemu.exe -L "h:\qemu\qemu\bios" -boot a -m 1 -fda "H:\VDisks\OS\warez\Dell330\Dell330-1.720" -hda "H:\Qemu\OpSys\Dos330.dsk" -nics 0 -dummy-net -isa -localtime -hdachs 60,16,63,none Boots the floppy fine. I can usually format the hard drive fine. (One version always fails the formating.) I can read and write to the hard drive fine. But when it comes time to boot the hard drive, every old version of DOS I've tried fails the same way. With the message: *** Booting from hard disk... Disk boot failure. *** I tried 6 versions of old dos (1 v3.2, 4 v3.30 and 1 v4.01) I even tried the -hdachs option thinking that might help. (I got the params from Bochs, so that should be right.) I tried enabling and disabling options, such as -isa and -std-vga None of that helped. Any ideas? Considering they do boot from the floppy, and they do work under Bochs emulator, I'm kind of figuring it's a problem with the command line. (That's why I tried the hdachs option. It didn't help.) Considering the problem is reasonably consistant, I'm kind of ruling out them being 'warez' copies of DOS, since I got them from several different places and they are behaving the same. But, on the off chance that it's a problem with qemu, I thought I'd post my 'help!" in the mailing list instead of in the qemu-user's forum, where developers probably rarely visit. So... Any ideas? _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
