hi all, really need help!

i downloadedd the rhel 4 AS and i got ready to install.

beforee installation i'd like to tell you about my machine:
H.W
Processor intel celleron 1.3
RAM 265+128 MB
sound and vga are built-in.
and MB solteck.
S.W:
rh9.0 and win2000

the problem is that, after downloading, i burn the 4 CDs and inserted the first one (not that my cd-drive works very badly), then i pressed <return>, then i choosed the language and the country and then he asked me to choose the installation media he gave me these choices (this process not found in rh9);
cdrom, hdisk, http, ftp and another one.

i choosed the cdrom but as i knoww my cdrom-drive is a bad one he toldd me to insert the media into the drive i tried more and more andd more but noway.

i remmemberd that i think i can do it from the hard disk, so i opened the rh9 puttted the cd in to the drive and issuedd:

#cd /mnt/mydisk
#where mydisk refered to hda5
#mkisofs -o firstcd.iso /mnt/cdrom

and booted again via the rhel4 first cd and in the process of choosing the installation media after choosing the lang and kboard, i choosed "hard disk drive "
he then asked me to choose;
hda3, hda5, hda7, hda6
i choosed of course hda5, but noway, can not continue installation he, asked me again to insret the installation media andd so on.
so please givee me step-by-step installation guide to install rhel4 from the harddisk.
thanx.

Try using your CD ROM. Watch for the boot: prompt and type in ide=nodam when you get it.

boot: ide=nodma

Essentially the original boot from the CD is done by the system BIOS. However after you've done the initial setup RH itself tries to control the CD at which point it assumes it is an IDE that uses DMA. For most machines that is OK but on an old Dell PowerEdge 1300 I had to do the above even though every other PowerEdge model I've done so far didn't need this.
