[Cialug] Transplant OS

[jrnosee at gmail.com]

Thanks for the quick responses!

I think I may try in order until one works....  I wasn't sure if Acronis
would handle Linux partitions, but I just got it free with the new drive I
bought from Newegg (combo deal)!  It'll be a local copy from a SATA II to a
SATA II drive and the new drive is bigger.  What I would like to know is how
to determine what hd(x,y) to use in grub. when I set it back up.  Typically,
yes I would use (0,0) but with SATA I'm not sure what # drive I'll be on.
Does this follow cabling order? 2x ide ports are 0-3, sata1-4 are 4-7?
Would my primary ide cd-rom be hd(0)?  I'm not sure what GRUB's numbering
scheme is.
