[Tfug] dual boot mystery

I'd sent a mail out a few days ago about dual-booting Linux and Windows 
with Windows in a slave hard-drive. I have a 120 GB HDD and a old 40 GB. 
Linux is on the 120 and WIndows is on the 40 (slave). Well I tried the 
suggestions by Jeremy, i.e, using map-drive and Lilo, but they didn't 
work for me. So I swapped the drives around but it turned out that my 
120 GB HDD didn't like being configured as a slave to the 40 GB. So I 
put the jumpers on both of them to CS, and put the 40 GB first on the 
IDE channel. According to the manual and IDE bus specs, this should make 
the 40GB the master and the 120 GB the slave. But the BIOS detected the 
120 GB as a master and the 40 as the slave.

Anyway, so I rescued the system and re-installed the boot-ladder (Grub) 
and now everything works fine. But here's the mystery... the partition 
info is still exactly the same. Linux is on /hda1 and windows is on 
/hdb1. SO nothing changed in the partition info at all from the previous 
instance. So what did change? Can anyone shed any light on this?

My guess is that the rescue disk did the grub install properly for some 
reason, because the local grub.conf file that I have in /etc is still 
exactly the same. A result of this is that I'm a bit apprehensive about 
re-installing grub from YaST because, it's probably gonna mess it up 
again. Is there anyway I can get the grub boot info from the MBR?
