I usually debug by adding dprintf statements. When that's too
painful, I connect gdb to qemu and set break points - the steps for
using gdb are in the README file. I don't know if there is a similar
way to connect gdb to a xen session.

As my last mail is still waiting for approval, I will resend it.
Hi all,
I am trying to boot Linux via Grub
from an USB stick. I have tried the USB stick on my devel i5 machine
and it worked.
Log can be found here: http://nopaste.info/2b119334eb.html
thanks

Intel provides a Linux-ready Firmware Kit, available on a LiveCD (79
MB) ( http://linuxfirmwarekit.org/download/firmwarekit-r3.iso ). You
only have to launch it, wait 1 or 2 minutes, and there is a summary of
the results based on different topics (memory handling, PCI resources,
HPET, ACPI tables, and more). The results is a number of "Fail",
"Warn" and "Pass" flags. This Linux-ready Firmware Kit seems to not be
developed anymore, but I guess it can give us a idea of the quality of
the BIOS.
Hello all,
The xen pv drivers are almost done.
When I start the booting process from hda seabios tries to read lba at
0 (sector 0) buffer (buf_fl) to 7c00 count 0 operation 0 (read)
command 1 (unlisted)
I do not understand count 0 and command 1.
Should it be count 1, for the first sector on the drive and a command
such as listed in drive.h?
Is this normal? Am I missing something?
Thanks,
Daniel
