Email me privately with a postal address. >>From the other docs it appears 0x122E is the ISA bridge and this laptop has 0x122E (PIIX bridge) and an 82437MX system controller, but no PIIX IDE. That actually suggests its more like the "MPIIX" which has a PIO only IDE controller existing (logically anyway) on the ISA side of the system. That would explain the observed behaviour and fit with the pattern of PCI identifiers. Now to hunt 82437 docs. (In the mean time try adding the 0x1235 id to the 2.6.17-mm kernel in drivers/scsi/pata_mpiix and see if that works with the new libata layer not drivers/ide). Alan
