It is WOW !!! In my experience the 2.4.3 kernel works the best on MDK 7.2 just make sure you upgrade your glibc (compile yourself) reiser utils and modutils,and hdparm it is all covered in the HOWTO'S Anyway have fun and let us know what the outcome is Stefaans -- GIF87an BTW if you have a ramdisk problem try another cdrom it worked for me! Just be carefull of dvdrom as they sometimes give problems. Now also use hdparm to enhance your disk performance just make sure you do have the hdparm that is correct for your kernel and that you do not have autotune in lilo when you boot that specific kernel. Also look at your dma and UDMA options in your 2.4.* kernels they make a huge difference Cheers Stefaans

Perhaps the kernel on the installation cd is set to something les than 2G? -- Alex Kernel Panic is General Failure's second in command
