My first machine, that is about 8 years old model, has SiS 5513.
It works here since I installed FreeBSD snapshot as of the end of 2003/05.

  atapci0: <SiS 5513 WDMA2 controller> port 0xfe80-0xfe8f,0x374-0x377,0x170-0x177,0x3f4-0x3f7,0x1f0-0x1f7 at device 1.1 on pci0
  ata0: at 0x1f0 irq 14 on atapci0
  ata1: simplex device, DMA on primary only
  ata1: at 0x170 irq 15 on atapci0

SiS 5513 supports WDMA2, However, some HDDs might freeze when they
detected by kernel. I *have to* type in following instruction

  set hw.ata.ata_dma=0

at loader prompt (or put equivalent into /boot/loader.conf) in order to
disable DMA and use PIO transfer for HDDs.

Recent FreeBSD 4.x would fail to boot because it does not have
src/sys/dev/ata/ata-chip.c, I think.  Soren, My understanding is OK,
isn't it?
