its better to upgrade to kernel 2.4.2 for better ide drivers. i run 6.2 on my asus cuv4x and when using the ide patches it didn't work when i had 2 ata-66 hd's installed.

having used the patches for a while myself, I think they work fine. I would not recommend running a 2.4 series kernel on 6.2 since the supporting utilities are NOT up to date enough.

BOFH, thanks for all the responses. Please bear with me, since I am a newbie when it comes to linux. What files do I need at linux-ide.org, and what do I do with them once I get them? I am using kernal 2.2.14-5.0 and last time when I tried to update the kernal through RPMs available from Red Hat resulted in a system that was unusable. I currently have a Maxtor DiamondMax 60 (45G, 5400 RPM)as master on IDE1 and two 45G 5400 RPM Western Digitals (not sure of model at the moment) on IDE 1 and IDE 2 of a mod'ed Promise Fasttrak RAID card.

Again, thanks to BOFH and all others that have responded.

Bofh out of curiosity what problems have you had with 6.2 and the 2.4 kernel? Modtools, and some logging stuff needs to be updated, but I've taken 2 machines to 2.4.2 with just 3 files.......

pretty much any distro will not have utilities up to date with 2.4 kernel, which is why theres a reason for the Documentation/Changes file which tells you what minimum versions to have before installing the new kernel, so saying not to upgrade 6.2 for that reason is kind of odd. most of the updated tools are already in rpm format and maybe one requires you to build from source, but its not that hard even for newbies. i've had experience running redhat 6.2 and using the patches and the new kernel. the drivers for the via apollo in the new kernel have allowed both my harddrives to operate at ata 66 as opposed to the patch only working when i had one harddrive installed. i've used 2.2.14, 2.2.16, 2.4.1, and 2.4.2 under redhat 6.2 and with the ide patch you're going to have to recompile the kernel so you might as well just download 2.4.2 and just install that.

joe, if i were you and were upgrading the kernel i wouldn't use redhats. just get them off ftp.kernel.org, it might be confusing at first, but its the best way to get an understanding of upgrading and compiling the kernel. and even if you do mess up, as long as you still have your old kernel you can go back to that. a good resource for newbies such as yourself is linuxnewbie.org

I haven't had a good set of modutils. I haven't looked too hard yet either as I'm not running 2.4 all the time right now. The main problem I have right now is with vfat and that the modutils are unloading my sound mods.

Debian Woody/Testing has the right stuff for kernel 2.4. I run it right now on some of my boxen and it works fine. The 2.4 kernel also drops right in on RH 7.0 w/o problems.
