Just before the Unable to locate configuration file message, I got a message with TFTP prefix: /xbmc-netboot/
So I think that wouln't the problem. But to be sure i've added the path to the file. But still the same message.
I also found the folloing in daemon.log:
Code:

can you access the file from another machine using a tftp client supplying the same path as your diskless installation does (or should do)?

Hey,
Thanks for this really nice thing, but I'm having trouble getting it to run on a HTPC with a ATI graphicscard (onboard HD3200).
I could see in the Xorg.0.log, that it didn't find ATI, VESA and a third module, can't remember the name of it. I discovered by googleling around that I can fix this by installing the fglrx package.
Finally XBMC started fine, but only the first time. The second time I got an OpenGL error (XBMC needs hardware accelerated OpenGL rendering. Install a appropriate graphics driver). By trial and error I discovered that, if I remove the folder in the overlay directory for the specific HTPC I could start it again, but again only the first time. So apparently some settings are stored there, which is causing the error, but I can't find out what.
I get this error when I start the XBMC for the second time in the Xorg.0.log:
Code:
xbmc@xbmc-diskless:~$ cat /var/log/Xorg.0.log |grep EE
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) AIGLX error: failed to load OpenGL driver
(EE) AIGLX: reverting to software rendering
(II) XKB: generating xkmfile /tmp/server-F8D9B4EE1D9075AF4B1C23C75362EE93E14954A0.xkmDo you have any ideas how to solve this. I'm quite new at this linux thing, so please don't use to many linuxgeek words
Thanks

I have never used TFTP before. I have installed the TFTP client on windows vista. What command do I have to execute to do that?
When I try: TFTP 192.168.0.10 GET initrd.img I get a time-out error.
- opdenkamp - 2011-01-05 02:29
@JohnPollaert:
it looks like your diskless client can reach the server, or you wouldn't see any log entries.
it should be something like
Code:
TFTP 192.168.0.10 GET /xbmc-netboot/initrd.img@RavenDK:
stuff like that isn't really easy to do yourself if you don't know anything about linux as you stated in your post. you'd have to install a package in the image.
if someone can tell me what the package is that is needed for those cards, I'll include it.
- JohnPollaert - 2011-01-05 09:22
The windows firewall was in the way. Now
Code:
TFTP 192.168.0.10 GET initrd.imgAnd:
Code:
TFTP 192.168.0.10 GET /xbmc-netboot/initrd.img- opdenkamp - 2011-01-05 13:04
I assume you verified that the file is present on that server in /var/lib/tftpboot/xbmc-netboot/initrd.img ?
are you running tftpd-hpa? if not, install it. then open /etc/default/tftpd-hpa and add "-v" to the options. restart the daemon with /etc/init.d/tftpd-hpa restart
now try to access the file again from your diskless client or windows machine and have a look at the log.
- JohnPollaert - 2011-01-05 21:22
Thank you! That did it. After adding the -v option I was able to see in the log that all the needed files where in the /var/lib/tftpboot/ folder, and not in /var/lib/tftpboot/xbmc-netboot. After copying the files over to the correct location, it started working!
Thanks for your help!

One of my clients is an Acer Revo 3600. It is having the exact same issue as drefas has. Does anyone has a solution for this problem?
drefas Wrote:Thank you for a great product!
However, i'm having a weird problem on one of my clients. It starts booting from PXE, after the first splash screen it fails to receive an IP:
Attempting to get a DHCP address...
info, udhcpc (v0.9.9-pre) started
Sending discover. . .
Sending discover. . .
Sending discover. . .
No lease, failing
dmesg is telling me this:
[ 2.850909] eth0: no link during initialization.
[ 2.851754] ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 4.023525] eth0: link up.
[ 4.024748] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 4.680443] eth0: link down.
The really weird thing is that if I unplug and then reconnect the ethernet cable, it receives an IP address and continues to boot. I'm getting the same behavior when setting a static IP in pxelinux.cfg/default.
When booting xbmclive installed on the harddrive, ir receives IP without any hiccups.
Hardware-wise, this is an Acer Revo 3600.
Does anyone know what to do?

looks like an issue with the network driver or the udhcp script.
adding a sleep before calling udhcp might help. I'll add a boot option so you can configure a sleep time before calling udhcp.
