The Intel ICH6 chipset is SATA, but, for reasons known ot IBM/Lenovo, the systems used PATA drives! So they has a SATA-PATA converter built in that screwed up a LOT of things, mostly compromising performance and generating assorted log entries. Looks like that also is broken in modern ATA support if a drive is not present. This was always my biggest complaint with this laptop (T42) which I used for several years until I retired and returned to so it could be excessed legally as it was government property (and, I didn't really want it, even if I could have kept it). Not an awful system, but this one issue was really annoying to me. -- Kevin Oberman, Network Engineer, Retired E-mail: rkoberman@gmail.com
