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

  The FreeDOS 1.0 ISO is confirmed to be working under normal PC BIOS when

  I guess your environment is a modern CPU with virtualisation extensions

  kernel have built-in support for acting as XEN client).

  FreeDOS 1.0 ISO works like this:
  1) Boot from CDROM in non-emulation mode
  2) Load isolinux.bin (old version, version 3.62 is latest release)
  3) Load isolinux.cfg configuration file
  4) Press 1 to load FreeDOS (loads Memdisk, then loads
  /ISOLINUX/DATA/FDBOOT.IMG, which is a compressed 360KB bootable floppy
  image file )
  5) FDBOOT.IMG gets uncompressed in RAM, then is being executed (in RAM)
  by Memdisk in uncompressed form.
  6) Bootsector is loaded, which in turn loads Kernel.sys (FreeDOS kernel)
  7) Kernel.sys goes looking for \FDCONFIG.SYS and if that doesn't exist,
  \FDCONFIG.SYS. If that also fails, \COMMAND.COM
  8) Selecting an option loads drivers and COMMAND.COM, then starts batchfile

  Knowing the layout of the 360KB diskette, I'd say the FreeDOS kernel is
  not able to find any files (don't see any menu option in your screenshot
  which points to no config.sys being found..nor can kernel find
  command.com). I don't know if XEN is to blame for this, or Syslinux,
  Memdisk or FreeDOS, or any combination of these issues.

  Could you refer me to the site which has a web-archive of the responses
  for the XEN mailinglists? Can't see if any threads with solutions were
  formed there.
  Alternative options are to remaster the ISO with 1.44MB floppy emulation
  enabled instead of non-emulation with Isolinux. Or ofcourse try a
  bootdisk first, instead of a bootable cdrom.

Re: [Freedos-user] [Xen-devel] Unable to boot FreeDOS 1.0

2008-03-23 Thread john s wolter
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.

  Any idea why is this happening? Error message attached.

 what we see until here is isolinux booting memdisk which boots
 a compressed bootable 360k diskette with dos from the cdrom...

FreeDOS kernel build 2036 cvs [version Aug 18 2006 compiled Aug 18 2006]

 copyright message about GPL2+ follows...

 - InitDiskBad or missing Command Interpreter: command.com /P /E:256
 Enter the full shell command line: _

 what you see here is that the FreeDOS kernel tries to boot from
 a disk which it cannot read at all. 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.

PS: Feel free to forward to other lists. Maybe you can add some
spambot protection when mentioning my email addr there, though.
