Dear coreboot folks,
this question is off-topic because the board is running the vendor BIOS.

I had to replace my hard drive and bought a new SATA-II disk.
Unfortunately the full speed is not detected. Instead of UDMA/133 – as
was used with the old SATA-I disk – it is reporting UDMA/100.

Here seems to be the problematic line, that somehow the drive is
reporting the wrong maximum speed or the chipset does not detect it
correctly.

So I am posting this question to the coreboot list since you guys having
ported the Asus M2V-MX SE to coreboot probably know of some limitations
of the VIA chipset and how to solve this. If not a pointer to the
correct list would be nice.
Thanks,
Paul
