Sorry, my mistake.
That doesn't help my feeling that most Adaptec IDE RAID controllers are,
in my experience (YMMV, and please excuse my language), utter crap,
though. Highpoint, 3Ware, and even Promise are lightyears ahead when it
comes to stability, supportability and performance (mainly due to the
Adaptecs having a nasty tendency to spew interrupts like mad, making the
system (interrupt) load go berzerk during heavy disk I/O).

The asr is most definitely not ;)
