Not only that, but that standard kernel won't recognise more than 1 GB of RAM. You need to install the enterprise kernel. Its on the first cd: kernel-enterprise-2.4.19.16mdk-1-1mdk.i586.rpm but note that there was a security update on the kernel packages 05 February 2003 - now using kernel-enterprise-2.4.19.24mdk-1-1mdk.i586.rpm. A word of warning: if you have a nvidia graphics card and intend to use the nvidia drivers, you _may_ not get them working with the enterprise kernel, even though there are nvidia drivers specifically for the enterprise kernel. I have tried nvidia's enterprise, source and tarball drivers, as well as Mandrake Club's enterprise drivers and Ranger's drivers all to no avail. And yet a separate installation with the standard kernel works with absolutely no probs. Its difficult to find help with this matter because very few people use the enterprise kernel. I've given up looking for a solution. Cheers Sharrea -- The box said "Requires Windows 95 or better" so I installed Linux ------------------ Mandrake Linux 9.0
