No DMA support

[Richard Warburton]

I have an AMD 64bit System with the 64bit Fedora installed.  
Unfortunately, I have two issues with it.

1) Fedora does not recognise the onboard lan.  I have fiddled bios 
settings with plug and play os and enabled the lan etc, but to no 
avail.  Problem circumvented with PCI ethernet card.

2) I cannot get the dma on the harddrives to work - which doesn't make 
it much good at serving files. 

I've searched the Fedora list back to volume 8, to no avail.  Googling 
suggests that I need to recompile the kernel with support for the 
chipset that my motherboard (ASUS K8S-MX) uses.  Is recompiling the 
kernel going to give me the option for this chipset?  Different types of 
drives (Maxtor 300G & Seagate 200G) do not appear to make any difference.

Any help or suggestions gratefully received.
