I checked ECS P4M900T(VT8237A) mainboard,
This mainboad has SATA controller vt8237a,
and my SATA HDD was not found.
I checked sata_via.c and result of lspci,
and seems it doesn't have pci_device_id.
I add pci_device_id 0x5337 to sata_via.c.
it works very fine.
and I also checked ASUS P5V800MX REV1.04G (vt8521)
PATA CDROM was not found on this mainboard.
I tried same way, add pci_device_id, works well too.
attempt patch to kernel 2.6.19 .
if you have same problem, try to this patch.
