I've got an Intel SRCS14L RAID Controller:

cp0: interrupting at ioapic0 pin 22 (irq 11)
icp0: model <SRCS14L>, firmware <Firmware>, 2 channel(s), 64MB memory
icpsp0 at icp0 unit 100: physical SCSI channel 0
scsibus0 at icpsp0: 16 targets, 8 luns per target
icpsp1 at icp0 unit 101: physical SCSI channel 1
scsibus1 at icpsp1: 16 targets, 8 luns per target
ld0 at icp0 unit 0: <PD_A000>, type: RAID-1, status: optimal
ld1 at icp0 unit 1: <PD_B000>, type: RAID-1, status: optimal

The Intel card works fine and delivers good performance (I'm using two
RAID 1 volumes). The disadvantages are that I need to use the BIOS or
an DOS boot floppy for RAID management or S.M.A.R.T. checking.

        Kind regards
