Let's have first some background before breaking it all ;-))

I have a board with 2 IDE ports (HighPoint's raid) and 2 "normal" IDE
ports. That's why I had to add those 2 disk-stanzas.... I will describe
the issues in my board (that might be quite similar to your case):

At startup, BIOS makes raid to be ide 0 and 1, and normal ones 2 and 3.
It then tryies to boot from first drive in the first ide available.
Let's say it is a master drive in ide 0. We should call it hda. So far
so good.

The "problem" is that Linux does not use BIOS to do it's I/O, so as soon
as it has been loaded into memory it won't use BIOS conventions. In my
case it thinks normal ide port's are 0 and 1, and raid ones are 2 and 3,
just the opposite as BIOS stated!!!

That's all. All you have to do to make thinks easier is to think is how
to force a remapping of ide's so as to be the same as BIOS, and you'll
get rid of many mistakes.

For example, if Linux mappings of hard disks does not match with BIOS
ones, and you run lilo to update mbr (OS boot menu) on hda, that drive
might not be first drive for BIOS, so it will boot another mbr and
you'll be wondering why you are booting with the same menu as always,
but nothing to do with the one you have spacified!! All this can be
solved by typing into lilo.conf the spells of remaping drives (or by
specifing boot=/dev/hd<your_BIOS_boot_drive>, but taking into account
that drive is the letter of BIOS remapped to what Linux wnted/was told
to).

Remapping can be done with disk's or map-drive spells (use disk's, cause
map-drive is mainly for DOS and the first one can be used with all OS
and it's clearer). Anyway, what you specify is:
 real_drive  -->  how_I_want_it_to_be_seen_by_the_OS


Now to your point:

Try to coment out those 2 stanzas and run lilo to see if Windows will
boot. Sincerely, I can't see a reason for them to be there provided
there is not a previous remapping of drives in lilo.conf. Anyway it
probably won't change much if all partitions in hdf are invisible to
Windows.


Good luck, and tell us what comes out.
