When the ServerWorks IDE controller was added to pciide(4) the
serverworks_chip_map() was missed being updated to set the UDMA
capability field for the controller as appropriate so at the
moment all devices connected to said controllers will only use
UDMA mode 0 instead of whatever they're actually capable of
such as mode 2 for a CD/DVD-rom drive for example.
pciide1 at pci0 dev 2 function 1 "ServerWorks HT-1000 IDE" rev 0x00: DMA
atapiscsi0 at pciide1 channel 0 drive 0
scsibus0 at atapiscsi0: 2 targets
cd0 at scsibus0 targ 0 lun 0: <TEAC, CD-224E-N, 1.AA> ATAPI 5/cdrom removable
cd0(pciide1:0:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 0
^^^
So if you have a system with said controller and can actually
test the CD/DVD-rom drive which is typically connected to this
controller (or HDs if possible too) then please test this.
