Dear list, I''ve tried booting FreeDOS 1.0 with Xen 3.2.0 and with the lastest 3.2.0-testing (changeset: 16817:d1d4cff0b3e4) without success. Using Linux 2.6.18.8 available at xen.org. - I''ve checked md5sums and everything is OK. - I tried with QEMU 0.8, available in Debian 4.0 and it worked fine. - I''ve burned the ISO and booted it directly in my machine, it worked too. Any idea why is this happening? Error message attached. kernel = "/usr/lib/xen/boot/hvmloader" builder=''hvm'' memory = 32 name = "freedos" pae=0 acpi=0 apic=0 disk = [ ''file:/root/hd.img,ioemu:hda,w'', ''phy:/dev/hdc,hdc:cdrom,r'' ] device_model = ''/usr/lib/xen/bin/qemu-dm'' boot="dc" sdl=1 vnc=0 vncpasswd='''' stdvga=0 serial=''pty'' Regards, Miguel _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Hi Guys, 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/ See Ya, Geraldo ps: sorry for crossposting, at least i hope it helps :) -- São Paulo, Brasil, -3gmt site: http://extremedev.sf.net msn: geraldo_boca_at_hotmail.com skype: geraldo-netto icq: 145-061-456 On 20/03/2008, Miguel Filho <miguel.filho@gmail.com> wrote:> Dear list, > > I''ve tried booting FreeDOS 1.0 with Xen 3.2.0 and with the lastest > 3.2.0-testing (changeset: 16817:d1d4cff0b3e4) without success.

[Xen-users] 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 <bblaauw@home.nl> 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. > I guess your environment is a modern CPU with virtualisation extensions > present and enabled?
