[linux-audio-user] Low latency kernel on Mandrake

Hi. I'm confused about whether or not I have a low-latency kernel, and if not why not. I installed the multimedia kernel and booted into it but: [root@olaf joe]# cat /proc/version Linux version 2.4.22-21mm.1mdk (dtholen(a)klama.mandrake.org) (gcc version 3.3.1 (Mandrake Linux 9.2 3.3.1-4mdk)) #1 Tue Oct 28 15:05:18 CET 2003 [root@olaf joe]# cat /proc/sys/kernel/lowlatency cat: /proc/sys/kernel/lowlatency: No such file or directory Does this definitely mean I don't have low-latency? Any ideas why not? Can't identify anything relevant in /var/log/messages. Does /proc/sys/kernel/lowlatency relate to the pre-emption patches or Andrew Morton's low-latency patches or both or what? Thanks for any help.
