Re: graphical console problem
Try to pass "video=sisfb:mode:none" to your kernel, just like pass
vga=ask. This options tells kernel does not turn on the sis framebuffer.
If this option works, you will bootup your machine in text console. At
that point you can try to activate standard framebuffer by passing
"vga=791" to your kernel.
