Here:
00:07.1 IDE interface: VIA Technologies, Inc. VT82C586 [Apollo IDE] (rev 06) (prog-if 8a)
Flags: bus master, medium devsel, latency 64
I/O ports at 6400
----------
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later
Split FIFO Configuration: 16 Primary buffers, threshold = 3/4
0 Second. buffers, threshold = 1/2
ide0: BM-DMA at 0x6400-0x6407, BIOS settings: hda:DMA, hdb:DMA
ide0: VIA Bus-Master (U)DMA Timing Config Success
hda: QUANTUM FIREBALL SE4.3A, ATA DISK drive
hdb: CD-ROM 36X/AKU, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: QUANTUM FIREBALL SE4.3A, 4110MB w/80kB Cache, CHS=524/255/63, UDMA
hdb: ATAPI 32X CDROM drive, 128kB Cache
As you can see, I do have a VIA chipset (MVP3), and a Quantum harddrive,
though it is an SE, and not ST.
Everything is working just fine.
