UIDE etc. (07-Jun-2011) (Announce)

Jack Ellis has released a new version of UIDE etc. on 07-Jun-2011.

Website: http://johnson.tmfc.net/dos/driver.html

Changes:

> I rather quickly decided that /X in UIDE and UIDE-S was "Not
> the best idea!". Although /X saved 320 HMA bytes, this did
> not justify losing 5% of protected-mode speed, due to having
> no binary-search buffer for fewer XMS moves! So, /X is now
> deleted, and both UIDE and UIDE-S shall always set a binary-
> search buffer from now on.
>
> When necessary, users can save HMA by loading the drivers in
> upper- or DOS memory, which saves a lot more HMA than merely
> 320 bytes! Also, UIDE now has a /M switch to set a minimum
> 256-byte search buffer, not its usual 512. If a DOS kernel
> is "almost full" and lacks only a few bytes of HMA for UIDE,
> /M might permit the driver to load in HMA space and so avoid
> having to load in upper/DOS memory. UIDE-S will ignore /M,
> as it sets a 256-byte search buffer in any case.
>
> Finally, the /N3 "No XMS" switch and the "default name" when
> no CD/DVD drives are present have both been deleted from the
> UIDE-S driver. This permits UIDE-S to be a 7.5K .SYS file,
> for diskettes or other "boot" media that need to save space.
> Users who want /N3 or default-name logic (FreeDOS autoloader
> "scripts", etc.) can use the regular UIDE driver, which will
> always have these features.
