hey radha,
well i went to the same thing myself....
just had to install it on a normal IDE(non sata) drive eventually....but you shud try somethings first..
a lil bit of gyan tho...
normal ide's are Parellel ATA and what you have is serial ATA(SATA) which is newer technology....
red hat 9 will not detect the SATA drive,so you ll need to find the
required driver for your SATA....
this ll be acc. to your motherboard chipset sata specifications....
for eg i have a via chipset based mother board and i needed to download a driver for via 8237.
anyway this is what i suggest you do->
STEP 1>look out for SATA drivers for linux in your motherboard CD.if you find it here you are really lucky.
STEP2>if not ,find out the exact chipset of your mother board,and search for a driver on the net.
STEP3>if you are successful in any of the first 2 steps then,make a lil' floppy disk acc. to intructions which ll have to be inserted at the time of the install.
if you cant do this,do what i did...install it on a normal IDE 4gb should do...and then pray real hard for the drivers!!
