"RAMDISK: couldn't find a valid ramdisk image starting at 0" and FC4 installation

[Mark Ryden]

Hello,

I tried to install Fedora Core 4 on 64 it PC (Intel Xeon CPU) with a SATA disk.
I got the error, in a very early stage of installation:

"RAMDISK: couldn't find a valid ramdisk image starting at 0"

I verified my installation disks were OK (by running "sha1sum").

Then I googled for a solution for a similiar problem, and it took
me a lot of time without a solution. After almost giving up
and starting to think of a different distro, I reached the
following thread in some Israeli linux mailing list:
http://mirror.hamakor.org.il/archives/linux-il/06-2005/15959.html

First I did not believe what I saw. Then I tried it (first enetring
gibrish and afterwards "enter" ) and ... it worked !!

My question is :
1) From where is this "RAMDISK: couldn't find a valid ramdisk image
starting at 0"
error ? What does it mean ? Is it has to do with that I have a SATA disk?

2) Is there no other solution ? (It seems not so much a proper way)

Regards,
MR
