Johnson Lam has posted a new 16-Oct-2011 DRIVERS.ZIP file on his website at <http://johnson.tmfc.net/dos/driver.html>.
In it, UIDE has again been reduced down to a 7.5K-byte file, same as UIDE2, for "boot" diskettes and other systems having limited space. So, UIDE-S is no longer needed, and it has been eliminated! UIDE2's performance is also improved, and all other drivers have merely been re-dated to 16-Oct-2011. To get UIDE below 7.5K, I had to delete its /M switch. /M saved only 256 bytes of HMA, "not enough" to matter, as UIDE uses only 4336 bytes of HMA in all cases. Even poor MS-DOS V7.10 (short on HMA due to long-filename and Win95/98 logic) still has 9100+ bytes of free HMA, and a "BUFFERS=4" command in CONFIG.SYS can reduce what the kernel needs! Most other DOS systems have MUCH more free HMA and should be no problem if loading UIDE with a /H switch. UIDE can be re-assembled with "SBUFSZ equ 256", if anyone absolutely requires its 256 byte binary-search buffer (runs maybe 1% slower)! The UIDE2 driver now runs a "hair" faster for protected-mode users, due to re-adding the old "ScnD" subroutine which uses a "scasw" command (not a full binary-search) in deleting old cache-table entries. "ScnD" is used with UIDE2's /H or /HL switches, as its HMA caches are small enough for such logic. Large caches in upper/DOS memory still use the current UIDE2 "SrchD" routine, for better speed with bigger search tables. The "UIDE" caching drivers now consist of only -- 1) The UIDE.ASM source file (assembles both drivers). 2) The UIDE.SYS driver for up to 4-Gigabyte caches. 3) The UIDE2.SYS driver for "fast" caches in protected-mode. I hope such a "simplification" is of benefit for UIDE users! ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
