Even if the BIOS can only see 8G, Linux should see and use then entire disk quite happily. It doesn't depend on the BIOS for that info. If you want to use windows as well, you may need to create an initial 8G (or less) partition for it. You could then boot the disk with no problems.
But: If you want to use your new controller card, you will need either of 2 things (so far as I know, these are the only ways) - 1. If the BIOS supports it, tell it to boot from the SCSI device. I know it's not SCSI, but for booting purposes the BIOS will treat it as such. Everything will look normal once it has booted. (I have done this on my own machine.) 2. Failing that, you will have to configure a boot floppy and boot off that. Brian Schroeder.

Subject: [expert] hard disk booting issue IBM PC.

Hi guys,
I've finially decided to fix an issue that has bothered me for ages,, I'm
just not sure its possible..
so I figured I'd ask you guys.
Anyway, I've got a 300PL IBM PC.
Its got a 40gig hard disk in it..
by itself the bios doesn't recognise the drive (see's it as an 8gig).. so I
bought a PCI controller card and plugged it in.
after hooking it all up, the card's bios see's the drive and reports its
stats perfectly..
but I still can't boot from it... I still need to use a boot floppy.
I've tried installing lilo in different places with different configs, but I
am not sure what else I can do.
regards
Frank
