Re: Network boot of RS/6000 CHRP systems
Dear sir, My company just bought a second hand IBM RS/6000 F50 server. When i try to boot it, onfortunately, the screen remains blank. I removed the VGA card, en installed an other one, but still, blank screen. (no input signal detected) Can you help me out on this one ? You would be a great help to me. Many thanks in advance.

Perhaps it's the monitor? Have you tried using it with another machine? On 3/14/06, Maes, Roel [EMAIL PROTECTED] wrote: Dear sir, My company just bought a second hand IBM RS/6000 F50 server.

(no input signal detected) Please connect a serial cable, and try netbooting it through the serial console (console=ttyS0,9600n8 usually), and post the result of the serial log if it doesn't work for you.

Friendly, Sven Luther If your card is not supported, you may want to try passing: video=ofonly in the append line to the kernel. It should then use the already initialized screen from OpenFirmware. If your card has a DVI along with a regular DSUB15 VGA output, make sure that the machine does not detect the wrong output. This happend to me with a ATI Radeon 9200SE PCI MacEdition, my 43p Model 150 randomly chose one on boot time but never probed both properly. Another card that works, is a Rage128 PCI usually found in older BW G3 Powermacs. In any case, I second Sven's suggestion to use a serial console as it is probably the most reliable solution. Cheers!

Well, I don't know if a PREP/CHRP hybrid exists but mine is a CHRP: [EMAIL PROTECTED] ~]$ cat /proc/cpuinfo processor : 0 cpu : 604r clock : 374MHz revision: 49.2 (pvr 0009 3102) bogomips: 372.73 machine : CHRP IBM,7043-150 And it is indeed a RS/6000 43p Model 150 as case and Open Firmware splash say. I tried a regular x86 compliant PCI 2.1 gfx card the other day (S3 VirgeGX) and it didn't work. Btw, this machine boots with either yaboot (1.3.14rc1) or using OF bootp, so I guess it is that it is in fact compatible to OF cards to some extend. in the append line to the kernel. It should then use the already initialized screen from OpenFirmware. If your card has a DVI along with a regular DSUB15 VGA output, make sure that the machine does not detect the wrong output.

Yes, the card that comes with it does not work with Linux as you say. Another card that works, is a Rage128 PCI usually found in older BW G3 Powermacs.
