Dual boot XP/pro and linux (lindows)

[Joel Hammer]

Thanks for the detailed response. I really do get confused with booting
issues. I recall well when I first started with linux, I decided to
really understand the boot process. Now, all I care is if it works!

In this case, the suggestion to use the map-drive parameter solved the
problem. I will just add some detail here so others may benefit.

I bought a lindows computer with linux on the first hard drive. I
uninstalled this hard drive, and installed a new hard drive as the first
hard drive and installed XP on it. I then put the linux hard drive back as
the first hard drive and put the XP drive as the third IDE device (IDE2)
or as a secondary master (/dev/hdc). There is no /dev/hdb drive installed.

My entry for XP in lilo.conf is as follows:
other=/dev/hdc
        label=MS_W<>?_XP
        map-drive=0x80
         to=0x81
        map-drive=0x81
         to=0x80
                                

First, the label. I had typed just
label=XP
but something is smart enuf in lindows to recognize XP as important and
substituted the label you see above. This gives a nice WindowsXP with a
little R to show it is a trademark. I wonder why they went to the trouble?

Second, according to man lilo.conf, the above entry swaps drives C and D.
Now, being simple minded, I changed the 81 to 82 (hdc instead of hdb). But,
the 82's didn't work. So, I guess the bios assigns those numbers
sequentially to installed drives only.  

So, everything works, even if I don't really understand it. Which, is just
fine with me!
