[Qemu-devel] VCPI & muLinux

[Qemu-devel] VCPI & muLinux

[Jim C. Brown]

I tried to install muLinux (a mini-distro, stored on several floppies) via the
DOS mode option. (The DOS, in turn, was running under qemu on my linux system.)

Suprise, suprise, it failed. Apparently, muLinux loads up Linux to run the
installer. Linux, in turn, needs loadlin.exe to load. And loadlin.exe needs
VCPI, which qemu doesn't support (or so it seems anyways).

This is not a big deal at this point (I can just hack the linux installer
script to install to image files instead of real floppies) but I am
curious: Are we going to support VCPI in the future?

BTW, does qemu support superformatted floppy images (as those made via
/dev/fd0u1722) ?

Qemu should be able to support all floppy disks types known by Linux. If
the format isn't recognized, it will use 1.44 MB as a fallback.
I didn't test all formats, but I succeeded to boot tomsrbt, which is an
extended disk image: 1.72 or 1.8 MB if I remember well,
and some other OSes with strange floppy formats...

Erm.. VCPI is API to enter/leave protected mode how can QEMU support it?
In any case all programs that need VCPI run just fine over here, given
that you have emm386(or substitute) loaded.
