Hi halvy...
The Disk is not new, I was using it on another "server" with Slackware (where the only problem was lilo). And the Disk is still working (its part of my new workstation
).
Ubuntu 5.04 said that there was no partitionable media (or something like that) with an ugly red screen.
Ubuntu 5.10 said that there was a disk... but it cant read the existing partitions nor use its partition software to do something with them.
Trying knopix is kinda useless, since my client wanted ubuntu... but thanks for your comment, Ill try it again later ^^
The computer is working now with an IDE Hard Disk and ubuntu 5.10 32bits, with that chipset.
There is a lot of messages about this issue, ubuntu is not the only distro with problems using SATA, especially with the SIS 5513
Thanks for your answer
Kenrro.
