Hello,

(In reply to comment #50)
For the partitioning: why can't we fake a "geometry" that allows for e.g. 4k
alignment AND looks sane to ancient BIOSes?

There just doesn't seem to be any which all the different BIOSes could agree on
which is aggravated by the fact that in many cases the first partition goes
over the CHS addressing limit so the BIOS doesn't even have enough parameters
to match up CHS and LBA addresses. :-(

Another worry that I have is about deviating from what windows is doing.
Vendors are testing their BIOSes against how windows is doing stuff so
deviation might (I almost wanna say 'will' here) lead to strange unexpected
problems for relatively modern and future configurations which is usually more
important to properly support than older machines.

Thanks.
