Re: [Freedos-user] [Xen-devel] Unable to boot FreeDOS 1.0
Hi Guys! How are you all doing? Bernd, actually, i don't know because, it is Miguel's host Miguel, can you provide details of your hardware? Do you know if your pc supports any virtualization instruction? ie: on intels vt instruction or on amds svm instruction? if you use linux you can try: 'cat /proc/cpuinfo | grep vt' on intels or 'cat /proc/cpuinfo | grep svm' on amds and archives is here: http://lists.xensource.com/archives/html/xen-users/ but i was not able to find out a solution Kind Regards and Best Wishes, Geraldo ps: sorry for crossposting again guys, does anyone have any clue? pss: sorry for posting the image Eric, my fault here :( psss: i updated my site, there i finally managed to put online all FreeDOS docs which i have here and some of them are translate (well, since many years ago...) check it out on http://extremedev.sf.net/freedos On 23/03/2008, Bernd Blaauw [EMAIL PROTECTED] wrote: Geraldo Netto schreef: Hi Guys, Hello Geraldo, It seems command.com is missing could you try any iso from this site? http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/ The FreeDOS 1.0 ISO is confirmed to be working under normal PC BIOS when booting from CDROM.

Re: [Freedos-user] [Xen-devel] Unable to boot FreeDOS 1.0
I don't believe the Xen environment has the capability to directly boot images from CD. I read an article in the Jan. or Feb 2008 issue of LINUX Pro from the UK, where they could not boot a CentOS install CD/DVD. They had a method of booting using a QEMU image as I recall from the hard drive. Next the QEMU PC emulation booted the CentOS CD/DVD. The article portrayed this a workable technique. Since I have yet to try that I can not say if this technique could be adapted to the FreeDOS iso image.

It does not open config sys, it only tries to open command.com because this is the default. Either the memdisk failed (int15 ext mem copy problem maybe?) or the kernel tries to boot from C: on a system which has no real or virtual harddisks visible to DOS (which uses the BIOS) at all. You see that InitDisk does not list any partitions, for example. Eric PS: Feel free to forward to other lists.
