The autoinstall option in the standard installation CD assigns 6GB to the / partition if a hard drive is >14GB, 1GB in swap and the rest as /home.

Hm maybe 6GB is a bit tight. Perhaps a third tier could be introduced, say 15 GB for HD over 50 GB (nowadays by far the most common situation?)

hi again, just to things more clear , i have two separate hard drive ATA, in everone there is about 250 gigabyte , the main one was sda , then i bought another one , i add it , and now it's called sdb . the problem i had is to install salix on the second one = sdb , but no joy :oops: i was like in a war with lilo and mbr , reinstalling salix for nearly 10 times :D , for a noob like me people will say it's okay by the time you'll learn :) .

anyway back to the problem , so installing on the second drive doesn't work , i get back to sda drive , means the first one

things was okay , and i get what i was looking for the root partion now is about 40 gigabyte :D , maybe some will say why all this for root partition , you'll not need all that , :shock: , well just i want that size ;)

here is some info about the new installation

Installing on an sdb certainly works. Autoinstall will not, but otherwise it works. You'll still have to put lilo in sda, where the bios looks to boot your pc ofcourse.
