SubjectRe: kernel 2.6t9 SATA slower than 2.4.20
Hi

I have removed the IDE SiI driver now the hdparm buffered disk read are
now 15M again. So you are right the IDE does give better performance but
the SCSI SATA does need to be enabled. I Think ;\

Now I am trying to iptables working, then SELinux

Thanks
Shaun
