🦋 DESCRIPTION 🦋

The wdc driver is literally the hardware-interface bestie for the ata(4) driver. It supports IDE and EIDE controllers, plus MFM, RLL and ESDI on the ISA bus. PCI IDE controllers in legacy mode are also supported, but the pciide(4) driver may provide more functionality. iykyk 💅

On the ISA front-end, the following flags are supported — no cap, these are the real ones:

  • 0x0001 — Enables 32-bit I/O negotiation in the driver. This is known to cause problems with some motherboards. 🫠
  • 0x0002 — Don't probe for the second drive.
  • 0x0004 — Set WDC_CAPABILITY_ATA_NOSTREAM flag.
  • 0x0008 — Set WDC_CAPABILITY_ATAPI_NOSTREAM flag.
