Re: status grub2 port of grub-legasy map command

[John Stanley]

I have your preboot hooks patch incorporated into grub-r2106 along with 
a suitably updated version of drivemap, which remains flawlessly working 
with  2nd-harddisk Windows XP boots (grub being installed on the 1st 
harddisk along with Linux). Had to make a few minor changes to the 
preboot hooks patch to get it to build in r2106.

I have also incorporated  your mmap services patch as well (again with  
minor mods to build in r2106). My question at this point, is how best to 
incorporate mmap services into drivemap. I see that in 
mmap/i386/pc/mmap.c there is some sort of support for int12 and int15 
services. Should I incorporate the drivemap int13 handler here ? Looks 
relatively straightforward -- just insert the asm handler into 
mmap/i386/pc/mmap_helper.S and update mmap/i386/pc/mmap.c -- (except for 
how I place the mapped drives table), or, should I use the mmap.c code 
as a template for the drivemap int13 handler plus mapped drives table ?

thanks for any help/suggestions,
John
