Tricking lilo to boot a non-existent device


Hi everybody,

I have a Promise controller that supports two parallel IDE drives in addition to two SATA.
SInce I don't have any serial drives, I am taking advantage of the ATA 133 controller on it.

One slight problem, though - the parallel drives are not (yet) supported, only the SATA drives are supported by the kernel. Google "PDC20375 PATA" and you'll see what I mean.

Here's the trick, though. I moved one of the PATA drives as hdb and I was able to setup lilo to boot from it. Then I moved it back on the Promise controller and lilo was still able to boot it. I guess that the BIOS sets it up as 0x81 so lilo doesn't know it's on a different controller.

This drive isn't visible to Linux and I'm OK with that. But I would really like to make lilo boot it without hassle. There's another OS on it that shall remain unnamed, old, but still able to play games.

So, my question is: is there a more elegant way to make lilo boot this drive without physically moving the drive?

Thank you.

SOLVED!

Doesn't matter any more. I can now see my drives on the PATA port, thanks to a kernel patch. See here if you're interested.

Thank you all for reading.
