Can not get to the installation (10.5.2)

yep i've already done that, the PROBLEM is when it says

disk2s2: unsupported mode

it also says that it's unable to write the root, something like that, that it's read-only, i'm saying what i remember, cause i have only this pc.

the AppleNforceATA.kext thing, is different, it says that no drives are found, but AppleNforceATA.kext it IS found

thanx eddie, so i should try disconnecting the other hdds, and changing the hdd that i'm planing to use from one sata to other to see if it works?

i've already tried with the other hdd disconected anyways.

and what about the disk2s2: "unsupported mode" thing?

(by the way, it's not always disk2s2, when i tried swiching hdds or things like that, it was disk1s2, and on other ocation was disk2s3)

thanx, i've tried changing the udma mode a thousand times, and did not work anyways, i don't know what to do.

i've now noticed that when i boot from the old dvd, it does not search for drive units.

in the 10.5.2 it says at first "1 unit found-", and later "0 units found"

and after saying Launched version 5.0

it starts coming disk1s2: unsupported mode, again and again

there's just one partition on it, at least that's what acronis disk director suite says, the disk is empty, and new

Just in case, Not sure if will help but, try to De-Select your other HDD from the BIOS (put it to NONE) and try it again

The install DVD will always show that the root file system is read only, as it's on a DVD. If AppleNforceATA is not finding any drives then there is a problem as your vendor ID is supported. You could try moving your disks around, make sure the DVD is on the primary IDE channel, and just hook the one SATA port your going to use up. Completely disconnect the others.

You could try changing the mode of the drive in the BIOS, I can only guess unsupported mode has something to do with the UDMA mode. Or perhaps if there is nothing else on the drive try doing a fresh format on it first.

what partitions do you have on the disk already? whats on partition 2?

Try to reformat the disk with just as Fat32 and try again, not sure what else to try.

i get the "/Library/Preferences/SystemConfiguration/com.apple.Boot.plist not found" message when i boot the dvd... any suggestions to what might be wrong...?

If your getting that error from the DVD then you may need to try burning another copy.

ive tryed that, burnt with nero and imgburn... got some suggestions for burning...?
is there any other preperations i should do to my disk...? i have a whole disk to dedicate, as it will be my only os...

[cite] marazi:i get the "/Library/Preferences/SystemConfiguration/com.apple.Boot.plist not found" message when i boot the dvd... any suggestions to what might be wrong...?

mmmm are you sure that you set the partition where do you wanna install leopard as active?
in vista menu start->cmd enter->diskpart->select disk X(x is the number of your disk)-> list partiton->select partition Y(Y is the number of the partition where do you wanna install leopard)->active->exit
then put the leopard dvd inside the pc and tell if works
thats how i can help you men
cya

ive tried that...
but i think it might be my disk / disks thats the problem...
tried with a 10.5.1 dvd, and got an HFS error then the same message came up and it got stuck...

my system:
HP PavillionDV9000ea
AMD Turion 64 x2
Nvidia Nforce Chipset with Serial ATA Controllers
2 x 80gb ST98823A S SCSI Disc device on Unknown SCSI/RAID HOST CONTROLLER

this is getting soooo frustrating...
downloading the tubgrl 10.4.9 to try that one out too, even though i dont think it will work
so...
what can i do...?

An option you could try, instead of burning the ISO to another DVD, partition your disk into 2 with one of the partitions being about 8gigs. Burn the ISO to the partition instead of a disk. Try booting from the partition. You will need something to use such as ubuntu to format the HFS+ partitions. But they are easy to obtain and use, and it may be worth a shot.

ok...
will try that, but how do i "burn" the iso to the partition...?
