Revision History |
15-Oct-12 |
UHDD/UIDE again detect A: and B: diskettes from BIOS data, NOT "Int 13h" calls!
See section 7 of their README for details. Other drivers unchanged (re-dated
only).
|
4-Aug-12 |
UHDDJR deleted, logic now in UHDD! /B "Stand Alone" UHDD (no caching) reduced
to 1440 bytes! UHDD dismisses all UltraDMA logic with /E "Call the BIOS" or
/N1 "No disks" switches, saving 464 bytes! XMGR/RDISK/UIDE unchanged
(re-dated only).
|
2-Aug-12 |
Added the UHDD "disk only" caching driver, for systems not needing IDE CD/DVD
logic. UIDEJR deleted, replaced by smaller/simpler UHDDJR and UDVD2. UDVD2
caches CD/DVD data if UHDD is also used! New /UD switch in UDVD2 and UIDE,
to cache CD/DVD directories only (requires the new SHCDX33F). XMGR/RDISK
unchanged (re-dated only).
|
9-Jul-12 |

channel, is corrected. Many Thanks to Doug Beneway for discovering this
error! Other drivers unchanged (re-dated only).
|
25-Jun-12 |
UIDE2 deleted. Other drivers unchanged (re-dated only).
|
17-Jun-12 |

less than 7K bytes for "boot" diskettes etc.! Other drivers unchanged
(re-dated only).
|
24-Feb-12 |

|
18-Sep-11 |
UIDE2 error (non-cached CD/DVD input in protected mode) is corrected.
UIDE-S or UIDE2 now handle 8 CD/DVD drives! UIDE-S now uses a faster
512-byte search buffer, /M will set 256. Other drivers unchanged (re-dated only).
|
9-Sep-11 |
UIDE2 using fast protected-mode caching re-added. UIDE-S or UIDE2

memory, still 688 bytes using /H. Other drivers unchanged (re-dated only).
|
10-May-11 |
UIDEJR sizes minimized! "CD/DVD only" UIDEJR in HMA space (/N1 /H
switches) takes 176 upper-memory bytes, directly replaces "old"
XCDROM/GCDROM drivers! UIDEJR now runs 4 CD/DVD drives,
new /U8 switch runs 8 when needed. Other drivers unchanged (re-dated only).
|
2-May-11 |
