2001 Mar 08 - Build 2022
|
||||
-------- Bart Oldeman (bart.oldeman@bristol.ac.uk)
|
||||
+ Fixes MCB chain corruption fix (thanks Tom Ehlert and Martin Stromberg)
|
||||
Redirector fixes (CDROMs and DOSEmu lredir'ed drives appear to work fine now)
|
||||
UMB fixes
|
||||
Various recodings (dsk.c, prf.c, portab.h) to make kernel
|
||||
object footprint 3k smaller (Tom Ehlert)
|
||||
Fix handling of very long path names (Tom Ehlert)
|
||||
FindFirst/FindNext fixes (Tom Ehlert)
|
||||
Configuration for libm.mak is in config.mak (Martin Stromberg)
|
||||
NLS fix to include pointer to CharMapSrvc. Note: these are
|
||||
changes to automatically generated .asm files, but the
|
||||
generator (GRAB_UNF.EXE) is missing. (thanks Tom Ehlert)
|
||||
DosSelectDrv fix (Martin Stromberg)
|
||||
config.c always converts to upper case and handles dos=umb correctly
|
||||
|
||||
2000 Dec 15 - Build 2022
|
||||
-------- James Tabor (jimtabor@infohwy.com)
|
