Running the bios under the emu is tricky. It may be bailling out early although normally it prints a messge. Search the archives for info. You will probally have to add debug printf's to see whats going on.
Ok, yesterday evening I have found the testbios faq on the linuxbios page.
I have tried it twice.
1. extracted vgabios from fuctory bios. 2. bios get with dd command from /dev/mem
The result of first try I have described before, it happens nothing.
The second try seems to be more successfully :D The screen goes to black :D after a second. No more. The connected TFT holds the signal. There is a short flickering after 30 seconds I think. (The reason for no output on the console is the FB Mode. I have sometimes problems, if I start a normal program, than there is no output too and I need to press <return> for a while to get a prompt) The system is still running but the only way to get a new try is <ctrl><alt><del> to shutdown and reboot the system.
Than I have made tests with my host system, to see what happens. I get a vga.bin with dd and try it. (PCI Nvidia Graphic Card)
I get a lot of numbers on the console for about 5 seconds, than the screen switched to black and the monitor lost the signal and goes to stand by. The system is still running but only <strg><alt><del> helps.
Mmmh, both systems runs in FB Mode, could that be the reason for no more output? Should I try the bios on a real console?
What does USER Space mean in the wiki?
