I have the following VT6421A based card:
and have fixed a bug in viaide.c recently
and SATA disks work fine in -current.
viaide2 at pci2 dev 7 function 0: VIA Technologies VT6421 Serial RAID
Controller (rev. 0x50)
viaide2: bus-master DMA support present
viaide2: using ioapic0 pin 17 for native-PCI interrupt
viaide2: primary channel wired to native-PCI mode
atabus4 at viaide2 channel 0
viaide2: secondary channel wired to native-PCI mode
atabus5 at viaide2 channel 1
viaide2 port 0: device present, speed: 1.5Gb/s
viaide2 port 1: device present, speed: 1.5Gb/s
wd2 at atabus4 drive 0: <Hitachi HDS721616PLA380>
wd2: drive supports 16-sector PIO transfers, LBA48 addressing
wd2: 153 GB, 319120 cyl, 16 head, 63 sec, 512 bytes/sect x 321672960 sectors
wd2: 32-bit data port
wd2: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd2(viaide2:0:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)
wd3 at atabus5 drive 0: <Hitachi HDP725025GLA380>
wd3: drive supports 16-sector PIO transfers, LBA48 addressing
wd3: 232 GB, 484521 cyl, 16 head, 63 sec, 512 bytes/sect x 488397168 sectors
wd3: 32-bit data port
wd3: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd3(viaide2:1:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)
5.0.1 still has the bug, and I've sent a pullup request for netbsd-5:
though PATA port is still not usable.
(our viaide driver doesn't handle it)
The ebay page reffered above says it has three SATA ports,
but I doubt VT6421 supports third SATA port.
(its eSATA port is exclusive? mine doesn't have eSATA port)
