XT-IDE Universal BIOS

Introduction

XTIDE Universal BIOS makes it possible to use modern large ATA hard disks or Compact Flash cards on old PC's. You can then enjoy quiet or noiseless drives with more capacity than you'll ever need for old computers.

The XT-IDE Universal BIOS provides an “extension BIOS” to the original IBM BIOS, to allow for the use of the XT-IDE Rev02 and other similar cards. For a (possibly incomplete) list of known cards, see below.

XTIDE Universal BIOS can be used on any IBM PC, XT, AT or 100% compatible system. On AT systems you can use any 16-bit ISA or VLB IDE or Multi I/O controller.

Features

Some of the features included in XTIDE Universal BIOS are…

  • Supports up to 4 IDE controllers
  • Support for virtual drives via serial port, more information
  • Supports drives with any capacity (MS-DOS 7.x (Windows 9x) or FreeDOS is required to access more than 8.4 GB)
  • PIO transfers with block mode support
  • Hard disk autodetection
  • Autodetected capacity, both CHS and LBA, can be overridden to make drive appear smaller than it actually is
  • Hotkeys and optional Boot menu (included in official 15k builds) for selecting any floppy drive or hard disk to boot from, including hard disks that are not handled by XTIDE Universal BIOS
  • Compact Flash and Microdrive support
  • Support for most 8-, 16-, and 32-bit IDE controllers
  • Native support for QDI Vision QD6500 and QD6580 VLB IDE controllers …and many more.

source and binaries

FIXME: where is the latest source? There's over a dozen copies listed at https://github.com/search?q=xtideuniversalbios . Which one is the latest / best-maintained, or is the latest source somewhere else entirely?

Official beta releases are now quite old. It is recommended to use SVN builds before new beta is released (unknown when this happens). Thanks to James Pearce from lo-tech to host SVN builds here.
