Expand description

Stub Winbond83977 “Super I/O” chip + dual-floppy controllers

Unconditionally reports no connected floppy drives. Useful for VMMs that wish to support BIOS boot via the Microsoft PCAT firmware, without paying the binary size + complexity cost of a full floppy disk controller implementation.

IRQ and DMA channel assignment MUST match the values reported by the PCAT BIOS ACPI tables, and the Super IO emulator, and cannot be tweaked by top-level VMM code.
