Installation doubts

[x18]

When you say that with video="800x600", it "loops", what exactly do you mean? Is it an improvement over the previous situation?

It loads Xorg again and again without succeding.

Apparently your Silicon Motion GPU has 16 MB of memory.

I wonder which is the correct data. Windows says 4.
And that could be the point: does it works on 4 and not on 16?

fd0 is the floppy drive. Do you know whether it's supposed to work? Does it matter if it doesn't?

It works great on Windows and using some boot floppy disks, including linux mini-distros.
It would be logic to get it working on any OS.
It is important on old hardware, especially for managing BIOS.

dmesg

Code:

[   11.011638] floppy: module verification failed: signature and/or required key missing - tainting kernel

Edit: try Xorg -configure again. Is the error about "Not enough video memory" still there?

Not yet, just "open /dev/dri/card0: No such file or directory"
