Re: I am not able to enter into BIOS

I don't think your Matrox board would have an option ROM.

I don't have Matrox, I have ASUS P5W DH DELUX and SAPPHIRE RADEON
X1950XT 256MB GDDR3

Think carefully, about how you have reconfigured the computer recently.

I don't remember, I have done some tries.
But now I remember I have converted the (D) disk in Dinamic. But in
the BIOS I have conterted it at Base again.

Did you recently flash upgrade the BIOS ? Maybe that changed something ?

I didn't upgrade the BIOS.

.... but the greatest mystery is the CD of Motherboard. When I try to
install drivers, a writing tell me they are not compatible with Win 7
32 bit. I have instalkled other times those drivers without problems.
Only this time I get an error.

In Device Management in storage controller now I see one entry only.
Some times ago I saw 3 entries: Intel(R), JMicron, Marvel.
