It is simply the result of someone who decided to add to the documentation that exists elsewhere.


XT-IDE and XT-CF variations/copies/derivations

Ordered roughly by year.


XTIDE Universal BIOS (XUB) - Versioning

The page at here will give you an idea of how the versioning of the XUB has changed through the years.

Within this web page, my convention is:
• 1.x.x means versions 1.1.0 through to 1.1.5
• 2.x.x means any version that displays its version on-screen as "v2.0.0"  (example: "v2.0.0β3+ (2019-02-14)")
• Rxxx means any version that displays its version on-screen as a three digit number preceeded by an R  (example: "r625 (2023-02-19)")

( Confusing the matter, most 2.x.x were often referred to by an 'R' number, but that number was not displayed on-screen. )

Note 1 Some XT-IDE/XT-CF cards can only use a CF card that supports 8-bit mode.

If a maker of CF cards decided to drop support for 8-bit mode, surely that would have been late in the design/production timeline.  Therefore, to increase the chance of 8-bit support, I suggest that you use CF cards of relatively small capacity, because they are likely to have been designed/produced earlier than larger capacity.

In the photos above of XT-CF cards that require a CF card that works in 8-bit mode, 4 GB and 2 GB sized CF can be seen.  Are those sizes a 'safe bet' ?  I do not know.

Of interest, is the 'Wed Oct 21, 2020 3:30 pm' post at here.
