The hard drive shows up as sda and the dvd as sr. The complete install only took 15 minutes. Configurated lilo also with append hda=noprobe.... After reboot the system sees the drive as sda. The speed change is huge. According to hdparm (with -Tt /dev/sda) the speed is > 90 MB/sec (it whas 1 MB/sec). So the solution here works perfectly, thanks a lot.

Yes that looks like SATA controller, did you try following the post? it shows more or less how to make it sda instead of hda..

good luck

The 250GB sata hard drive is seen as hda. lspci shows: 00:1f.2 IDE interface: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 4 port SATA IDE Controller (rev 02) ?? Is this a sata or ide controller ?? After opening the case the hard drive is a Seagate Baracuda SATA 250 GB. But can this controller be told to see the drive as sda instead of hda? Currently it is dead slow (hdparm tell me it is doing 1 MB/sec). Any advice welkom.. Just installed Slackware 12.1 on a HP Proliant ML110. The 250GB sata hard drive is seen as hda.

I made the changes you mentioned, got a maintenance window upon reboot. followed rest of the steps and it works now. Thanks for your help. P4C0,

At lilo promp add hda=noprobe hdc=noprobe libata.atapi_enabled=1 and boot (just to try), it's more likely that you will end up with a maintenance console in where you can mount your (new) sdaX root partition, chroot into it and modify fstab, lilo and recreate initrd (if needed). If no, you can boot with the slackware cd, mount your root partition and do the changes. Good Luck Hello Zixi,
