Hello!

kernel (redhat) : 2.4.18-14

I don't know why, but the AGP do not work on this chipset and the hard drive and CD-Roms do not seem to be very fast, like it could. Is it a problem with my machine or is it that the kernel is not currently supporting it. Will it be supported one day by the kernel if it's the problem ?

Thanks

Matt

The chipset isn't supported in that kernel. The AGP looks for a PCI ID that isn't defined and the ATA/133 is not supported at all.

Alan Cox has full support for it in his 2.4.20-XXX-acX patches and it works well.

Try modprobe agpgart try_unsupported=1
If that works, let me know the output of dmesg.
