I hade a similar problem, when I upgraded from Xfree 3.x.x to 4.x.x.
Unfortunaly I never figured it out instead I now use Xfree 3.x.x which
works fine. I don=92t have the same system as you but my problem seems
very close to what you experienced.

Perhaps not that helpful but there are more of us with the same
problem;)

hi,

i'm using xfree86 4.2 on netbsd 1.6, and my computer is a standard=20
lifebook 530t. i ran the autoconfig and the c&t adapter was found just=20
fine, but when i startx the computer just hangs. the last message in the

log is "chips(0): bad v_bios checksum followed by "chips(0): primary=20
v_bios segment is 0xc000". this happens shortly after loading module=20
"int10", which i believe is a vga mode. what exactly is that needed for=20
when my config is set up for 800x600@24bpp? anyway, the screen seems to=20
be in text mode still, since i do have a block cursor present in the top

left corner. i can't do anything a this point, not shut down the=20
x-server, not switch to a virtual console or anything. i found a config=20
file for a lifebook 555 which i borrowed the sync and modelines from,=20
but that didn't help.

the error i get seems to suggest there's something wrong with my bios=20
settings, but there aren't that many options to be set in the bios=20
setup. the docs for xfree86 talk about diabling caching and so on, but i

don't have that option. my bios says "video bios shadowed" during=20
startup, but i can't change that either. any ideas?

so, anyway, below is my xconfig. if somebody is using a 500 series=20
lifebook, perhaps you could email me your config so i can check for=20
differences?

(in case you're wondering, graphics are working just fine in win95, so i

don't simply have a broken computer) :-)

thanks a lot,
