Seems so.

Seems so.

I will check it later.  Somewhere in the middle.

No.  I installed RH6.2 on /dev/hda1, and then copied an entire partition of 
another HD onto /dev/hda2 (just like I did on the other laptop).  So, I ran 
lilo from RH6.2.  Theoretically, the situation is similar.  THe only 
difference is, on my laptop, there is only one primary partition (hence, 
hda1, hda5, hda6, ...), but I have 4 primary partitions on this desktop.  
Not sure if this is causing the trouble. Thanks!
