RE: large IDE disks (was Re: [SLUG] IDE Raid Controllers)

This is correct, but Linux will see them correctly even if the BIOS doesn't.

The only problem I can see is, that you cannot boot from the HDD (because
the BIOS does not see it or not the correct size) and you might have to boot
from floopy, but once you have booted Linux it will see the drive and use
its partitions to run.

speaking of this, someone told me "older" PCs have problems
with IDE disks above somewhere around the 60-80Gb mark.

"Older" being approx pentium2 vintage and earlier (not that
old IMO!).  And "problems" being that the BIOS doesn't
even see the disk therefore it can't be used under any
OS without a BIOS upgrade.

Now I find this hard to believe myself, but not having
an 80Gb disk to try it with can't say for sure.
Anyone heard of such a thing?

PS. this person also says the seagate 80Gb disks come with
some software that "remaps" the disk to make it work in older
machines but it causes a performance hit in M$ stuff (and
no they're not confused with LBA and that type of thing).
