Western Digital XT Hard Drive Controllers

WD 1002x-WX1/WX2 MFM hard drive controllers (ROM versions 62-000043-0xx known affected) have bugs that affect the ROM POST screen display of hard disk geometry (as well as other bugs affecting XT-IDE). If you use one of those, it is recommended to upgrade/downgrade your ROM to version 62-000094-032 (F300 BIOS "Super BIOS") or 62-000042-011 (without dynamic formatter). Otherwise, build GLaBIOS with POST_HD_CHECK = 0 to remove the display of hard drives at POST.
