Well as the title says I have an Asus K7V mothebroard and it's a great board but there are two issues I'd like to address two issues under linux Red Hat 7.2 with it.

The first one is that the nvidia drivers default to AGP 2x when the board supports up to 4x so I'd like to enable 4x. The doc said "You can force AGP 4x by enabling NVreg_EnableVia4x in os-registry.c and
rebuilding the NVIDIA kernel module." but I really have no idea how to do this.

The second issue with it is that a bug with RH limits the transfer speed to ATA33 when the board can go up to ATA-66. The first step was to repalce the via82xxx.c file with one supplied by VIA which I did. Then we had to install the source of the kernel if it wans't alreayd installed and kpackages told me I alreayd had it installed so that was good. But the next step was rebuilding the linux kernel and even though there were detailed explanation on how to do this, one of the commands they told me to execute fails so I have no idea how to do this still.

So my quetsion is, could someone please walk me through on how to fix these two problems ? If possible through one single kernel rebuild but that's not a must. If you'd like the IDE readme it's located athttp://downloads.viaarena.com/LinuxApplicationNotes/VIA RH7.2-7.1 IDE Beyond ATA33 ver 0.91.gz and as for the AGP 4x one, I already posted all the info they gave.

Any help would be greatly appreciated. Thanks.

edit : as a sidenote, I've read somewhere the the nvidia drivers could cause some kind of memory leak and would cause the system to use alot of resources but that it coulkd be fixed in some way. Anyone else heard about this and would know how to fix it ?

From the nvidia readme file,

I know, I've read it. But I'd still like to see what it does with my pc. But my priority would really be the IDE channels though. But the way they said I should do it is wrong. Or at leats it gives me error messages so how would I go about it ?

The problem is with the KX133 chipset, thats why VIA brought out the KT133 for socket A, the KX was designed for Slot A athlons.

I have a first generation athlon actually. when I bought that board it was one of the only ones for the athlons with 4x agp and pc133 ram support.

To compile your own kernel you should start by reading the kernel-HOWTO, and for AGP 4x you will need to download the NVIDIA_kernel-1.0-*.tar.gz and edit line 91 of os-registry.c, change it from
U032 NVreg_EnableVia4x = 0;
to
U032 NVreg_EnableVia4x = 1;
and then build the module.
