My new notebook uses a short 40 pin ide-cable, ata_piix therefore disabled UDMA>33. I added the chipset ids to the short-cable list and now everything working fine with UDMA100. regards --- --- linux-2.6.22/drivers/ata/ata_piix.c 2007-07-09 01:32:17.000000000 +0200 +++ linux/drivers/ata/ata_piix.c 2007-09-13 21:08:07.000000000 +0200 @@ -578,6 +578,7 @@ { 0x27DF, 0x0005, 0x0280 }, /* ICH7 on Acer 5602WLMi */ { 0x27DF, 0x1025, 0x0110 }, /* ICH7 on Acer 3682WLMi */ { 0x27DF, 0x1043, 0x1267 }, /* ICH7 on Asus W5F */ + { 0x27DF, 0x103C, 0x30A1 }, /* ICH7 on HP Compaq nc2400 */ { 0x24CA, 0x1025, 0x0061 }, /* ICH4 on ACER Aspire 2023WLMi */ /* end marker */ { 0, }
