Thanks Richard Urban!
I went to the website you gave me but i don't know more about the
motherboard that it is a PCChips M758LMR (Socket 370 Intel P3) and on
the download website i have to choose the version like (5.2 etc) and
just to be sure before to flash the bios i want to be sure that i
download the good version for the bios. The closer model i can see is
M758L+ (5.2) . How to know if this is the good one for me? Does the
plus(+) means all model that begin with M758L + anyother thing? If so
there's another model that is M758+(5.2). Does it only mean that it is
more general that the first one...i'm confused and i heard that not
using the good bios version can make your computer not booting so
that's why i'm asking maybe stupid question for you but i'm not expert
with those thing and i want to have advice from experts before to say :
Damn, look what you did fool!

P
I the bios update i saw
4.Fixed IDE can't run UDMA mode in Win 2k.
So i guess this can help me with my problem even if i don't have 2k but
xp...no?
Thanks a lot guys you are very nice!
