IDE Raid Issues

[jseifert]

I'm trying to install Gentoo on a four hard drives connected to a Promise IDE RAID (FastTrak TX4000).

It seems like the Gentoo installation CD correctly detects the card, and sees all four channels - but for some reason it detects the first two channels as SATA when they are actually PATA. Because of this, it is not seeing the hard drives connected to the first two channels.

From the dmesg:

Any way to force it to use PATA for all four controllers?

jseifert,

I suspect that the SATA being reported is the SATA from the motherboard, then its seing onlt the first 2 channels on the plug in controller a,d not even looking for the second two channels.

If you unplug the card are the first two SATA reports still present in dmesg ?

I suspect the choices are turn off SATA on the motherboard or make the kernel scan more IDE buses.

Neddy,

Thanks for the reply... I tried disabling SATA in the BIOS, and still had the same effect. If I pull the RAID card, I get no SATA devices at all...

However, I do think I fixed the problem.

It looks like the sata_promise driver that comes with the Gentoo Install CD *forces* the first two devices on the card to be SATA. This can be seen at this portion of the code:
---
probe_ent->port_flags[0] = ATA_FLAG_SATA;
probe_ent->port_flags[1] = ATA_FLAG_SATA;
---

I commented out the above two lines, recompiled this module on another gentoo system I have, and then copied it over to the system I am tryign to install... This module successfully detected all four drives and gave them all drive names.
