[Qemu-devel] Windows 95 and qemu

[Oliver Kopp]

[-- Attachment #1: Type: text/plain, Size: 563 bytes --]

Hi,

I tried qemu-cvs two days ago with a German Win95 using qemu -hda
/dev/hdc
/dev/hdc was the main harddisk of another PC, where Win95 works fine.

After firing up qemu, windows sys, it has an I/O-error and I should
change the disk.

qemu -hda /dev/hdc1 doesn't work either: "incorrect system" (or similar)


fdisk -l /dev/hdc gives correct values.

FreeDOS from www.ubcd.de 2.31 and qemu -hda /dev/hda -cdrom /dev/crom
-boot d showed a 0 MB-Disk while booting...


What can I do to use this Win95-Installation?


Greetings

Oliver

I have a similar problem:

with the latest (june 10) cvs qemu, when I do "qemu /dev/hdc" (the
main disk in my laptop on which I have a dual-boot WinXP / Linux), I
get the Lilo interface without any problem. When I choose to boot
Linux, it works fine. Booting XP however, gives me the message "A disk
read error occurred, Press Ctrl+Alt+Del to restart". GRUB gives me the
same result.
It seems the lilo bootloader jumps correctly to the XP boot record,
but from that point on something goes wrong.
Has anyone had success yet booting XP (or another windows) from a
device file?

The problem may be related to the fact that QEMU does not initialize the 
HDD geometry fields in the CMOS memory.

Could that also have something to do with the failures I have installing
SP4 on Win2k?  It seems odd that something that high-level would be
checking something that low-level directly, but it does fail while
"checking for disk space"...  I don't know, just wild speculation...
