This is the original XT-IDE Deluxe. I cannot comment on the quality of clones with credit and branding removed.
The XT-IDE Deluxe is primarily for adding a reliable, modern hard disk solution to an 8088 PC, such as an IBM 5150 or 5160. It also works in 286 and up, but the Monotech DoubleROM
card will provide you better performance in those.
The card provides both a rear-accessible CompactFlash card slot, and an internal IDE port for hard drives or internal CF cards. You can use both at once, with a maximum of two drives total. Typical uses:
By default the XT-IDE BIOS comes configured for:
- Add IDE HDD or CF card to an 8-bit ISA system such as IBM PC, XT, and clones.
- Add IDE support to a system without IDE support in the BIOS (like AT and PS/2).
- All-CPU-compatible BIOS.
- Use the XT-IDE Card's IDE interface at 300h, no IRQ needed.
- Boot first hard drive unless user presses A for floppy.
Any of the above can be changed on purchase, or in your own time with the simple DOS utility.
I recommend using the 186 BIOS if you have an 80186 or NEC V20/V30 or higher, for improved disk performance.Switches and jumpers control:
- I/O port for the onboard 8-bit IDE interface
- I/O port for the Option ROM
- Option ROM Enable
- Option ROM Write-protect
- Compatibility mode and HiSpeed mode
- Provide 5V on IDE pin 20, which can power some DoMs and CF adapters.
- IBM XT Slot-8 Support
There are blank PCB pads for an optional power output connector. Useful for powering an IDE HDD in machines such as the PS/2 Model 30, which doesn't have a spare power connector from the power supply.
You can upgrade to the larger 32K EEPROM. This has a boot menu and is only useful if you wish to boot from more than one HDD and Floppy drive at different times. The default 8K EEPROM allows booting from one HDD and one floppy drive (by pressing A). This upgrade is $5 more (make the offer if desired).
The CF slot is set to master by default, as some CF cards don't like being slave. You can change this with a jumper on the CF daughterboard.
Max 2 drives, one as master, one as slave.
So you could have one IDE drive on an IDE cable, and the rear-accessible CF slot populated.
Or you can have just the CF slot, or up to two IDE drives on an IDE cable, with no CF card in the slot.
