First hardwares on my machine:
Foxconn 755A01-6EKRS Socket 754 SiS 755 motherboard, athlon 64 3400+, 1G PC3200 ram, ati 9200 mobility, two 200G-sata, one 200G-IDE, one 160G-IDE.

Here is the problem: Mandriva 2006 hardly can recognize all my drives at the partitioning part of the installation, usually I could only see my two IDE drives and maybe one of the sata drives. So I restarted the installation, and finally I was lucky once to see all my hard drives and install Mandriva 2006 on a sata drive. But after installation the system would not boot up because the sata drives cannot be recognized by Mandriva 2006. Then I switched to the 160G-IDE drive to install the system, and this time I can login to the system, but I still cannot find any partition of my sata drives under /dev.

When I was using Mandriva 2005 LE, I had no problem to have all my drives mounted in the system. Does Mandriva 2006 have less compatibility than 2005?

Any ideas and suggestions? Thank you.
