The problem is that ICH7 chipset unable to report negotiated SATA speed. That's why only SATA reported there. UDMA100 report is also correct there (even if it looks strange). As SATA just wraps all existing parallel ATA protocols, from ATA protocol point of view that mode is active. -- Alexander Motin
