since the nforce2 ide wont work with latest cooker kernel:
kernel-2.4.21.0.pre3.1mdk-1-1mdk
I took Alan Cox ac4 patch and removed all but nforce2
patch and applied it to latest MDK kernel (above)...
(renamed it to: kernel-2.4.21.0.pre3.1TmB-1-1mdk)
It works great:
here is the hd speed with the MDK 9.0 kernel (on full Cooker):
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.33 seconds =387.88 MB/sec
Timing buffered disk reads: 64 MB in 19.11 seconds = 3.35 MB/sec
and here is the speed with my patched kernel (on full Cooker):
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.32 seconds =400.00 MB/sec
Timing buffered disk reads: 64 MB in 2.11 seconds = 30.33 MB/sec
So the patch is included with this mail.
And if you dont want to apply the patch yourself, go to:
http://www.iki.fi/~tmb/Cooker/
where you wil find:
- this patch
- precompiled 'up' kernel
- the kernel SRPM
To get the 3c920 nic on the nforce2 to work,
se my other mail......
