Post subject:  Problems getting MOLK to boot from CD
Hi all

I have just tried to get MOLK to boot. I edited the config files as described in the Pegasos Book, and when I booted MOLK I got a bash prompt. I typed "startmol -X --cdboot". The screen went black with a white flashing cursor in the top left corner. The DVD spins up and I can hear activity and see the activity light flashing. This eventually stops, but the screen stays black with the flashing cursor. If I switch back to the Linux terminal I see an error

Could not set VSCREENINFO: Invalid argument
Video transition failed

Every time I switch to the black MOL screen and back to the terminal, the error is repeated. I don't know if it's relevant or just because the video driver doesn't like me switching.

Any help would be much appreciated!

Don't know if this is relevant, but I'm attempting to boot a Tiger DVD on a PegII.

This is strange. As your cd-drive spins up the problem is probably not there. Maybe you have a monitor which doesn't accept my default screenmodes?
Maybe you should try to enter
molvconfig
in the bash & see if your own configured screenmodes give a screen...
good luck so far!

Ahhhh yes you could be on to something with the monitor. When I installed MOS I had to fiddle around a lot with the screenmode's frequencies to get it to display 1024x768 on my LCD TV. Does molvconfig let you reconfigure the screenmode MOL uses?

Thanks for your help

Hi!
Yes with molvconfig you can define valid screenmodes for mol! As the boot-partition containing also the mol dir is mounted readonly you can't save the config. So you'll have to remount the bootpartition rw in order to save!
good luck!

Ok, just just to clarify:

1. "# mount" to find the loopback root device
2. umount the loopback root device (can I do this while molk is booted?)
3. Re-mount the root device r/w

You have a bootpartition on your pegasos2 containing your linux-kernels, maybe the mos-boot-kernel & very likely the molk kernel & its friends (f.e the mol dir).
Boot molk as you did & get into in the terminal
Now remount your boot-partition with
mount /dev/yourbootpartition /booty -o remount,rw
here my bootpartition is /hda1 yours might be an other one!
molfconfig should now write its resulting config to /booty/mol/fb_modes (/your bootpartition is mounted on /booty & /booty/mol/fb_modes is symlinked from /var/local/mol/fb_modes where molvconfig usually would write its file).

If this doesn't work for you you could still mount an usb stick & copy the resulting fb_modes there manually... Then copy it from your favourite os to your bootpartition/mol/

cheers

You're amazing :D The Tiger installer is booting from the CD as I type and I can see Tux hugging an Apple with a spinning wheel!

Ooooh, it's asking me for a language now. This is exciting 8)

Thanks so much for your help!
