It does.

Unless you volunteer to change it, probably.  Even if the driver were
better, the AIC6[23]60 is a PIO-mode chip, which makes it suffering
the same performance vs. CPU-load problems like IDE.

Btw., since most machines these days are PCI anyway, you can always
recommend the SymBios controllers (formerly NCR) for a cheap solution.
They aren't only cheap, but powerful, and FreeBSD ships with a well-
working driver for them (...says Joerg, typing this on a machine with
two 53c810's).

Never trust an operating system you don't have sources for. ;-)
