Re: [Xen-users] Has anyone installed from an XP Pro "upgrade" disk
Hi,
I might be way off topic here, but from my experience you can boot and
install off the XP upgrade disk and do a clean install. At some point
it will ask you to eject the XP cd and insert your 98 CD to prove you
own a previous version. I believe you can do this with from other posts
I have seen. You don't actually need to use the win98 cd for anything
else. No actual upgrading has to occur. It's a license thing.
Apologies if this isn't what you're all talking about.
Ryan.

I don't have a full install, just the upgrade. I tried to
insert the
windows 98 disk but it didn't find that, I tried to dd a
working win98
partition to an image and use it as the image file,
thinking XP might
read that file, but that didn't work. I also tried to install
Win98 but
it failed because it tried to load a driver to read the cdrom and
couldn't.
I definitely haven't tried this, but I don't see why it
shouldn't work
(except perhaps Win98 is too similar to Win 3.1 and uses
based segments
rather more than WinXP/NT type OS's).
A driver to read the CDROM should work just fine.

When the 98 cd boots, it starts in a dos window and attempts to load a
generic cdrom driver, but eventually fails with a message
suggesting it
can't find a drive. I don't know enough about how a disk is
"virtualized" to know if this generic driver will find
anything. Win98
came about before it was common to have BIOSs that knew about CDROM
drives, if I recall correctly.
BIOS may not know about CDROM drive in ancient times, but the CDROM
driver (assuming it's an IDE one) should be able to identify the
emulated CDROM device [Do you add the ":cdrom" to your cdrom device in
the config file? - Otherwise it may not work].
The HVM domain just passes the device accesses to qemu, and it's
forwarding that to the Dom0 device itself after some translation, but
any identification should work just fine [unless of course the driver is
looking for something very particular in the device profile which isn't
satisfied by the emulated device, but I doubt it].
It may of course be that the driver doesn't play clean with regards to
how it accesses the device, or it may be that the driver is doing stuff
that the real-mode emulator (on Intel) doesn't like, for example.
