That's the problem, I guess. The RH tuned 2.4 kernels (I didn't test linus kernels) do IDE tuning without using hdparm. I can say the Promise controller performs very good. With a RAID0 on all four disks I get mor than 120MB/sec throughput (yes, the file is big enough to not use caching). It's was also very fast on i820 chipset but it seems not to be reliable. FYI I didn't touch hdparm. I'm just giving up on using multiple IDE disks with kernel 2.4. Sad but no choice. > > -- > Martin K.
