I have a very weird problem here; I have two systems here at home, one (A) is an athlon 1.4Ghz on a ECS K7S5A (rev.3) mobo with 256Mb of (good, Nanya) DDR-ram, a Creative sb128 (onboard audio has way too low output for my amp), a GeForce 2 ti, a 80Gb Western Digital hd on the first IDE controller and two optical drives on the secondary IDE controller.
The other system (B), my brothers actually, is basically the same; same mobo, bios version and settings. The difference is that it's got a 1Ghz athlon, 256Mb of (cheap but good) generic SD-ram (mobo supports both kinds of ram), a smaller hd, a GeForce FX5200 and no PCI soundcard.

So I recently upgraded from a GeForce 2 mx400 to a FX5200 because the old card had gone bad (prolly bad memory) and, guess what, can't run Knoppix anymore, at least not with X...
So far I have tried "xmodule=fbdev/vesa", tried to specify the screen resolution and refresh rate, "nodcc" and whatnot but Knoppix always hangs at the point where it should start the x-server. BTW, "failsafe" brought me a little futher; it looks like the x-server is actually being started but after a couple screen refreshs it says "no suitable x-server found" or something like that.

I'm really running out of ideas here, I mean I could always plug in another graphics card but thats not really the solution I'm looking for. And it's not the bios settings either; I made sure to disable acpi as I know that it causes data corruption, IDE devices not being found and all kinds of funny stuff depending on kernel version on this mobo...

anyway, I NEED HELP! any idea appreciated!

p.s.: has anybody else noticed that the syslinux prompt is all blue on the ECs K7S5A? Looks ok on any other system I've run knoppix on though
