Mapping drives

[David Anderson]

Hello,

I have linux on hda and a windows XP en hdb. I tried booting the
latter by chainloading it "simply", but it seems windows doesn't like
being on the primary slave...
So I'd like to try mapping hdb to hda, to see if that helps. However,
I have two questions about doing so: first of all, will windows be
intelligent enough about this not to damage my linux installation? And
secondly, once I have defined a map in grub, should my commands ignore
or take into account the mapping?

Thanks in advance
