2002 Dec 9 - Build 2028
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Tom
* move clock driver initialization to inittext
* new ELSE_ISFAT16 macro to save some bytes
* use _TEXT for old HMA_TEXT, _LOWTEXT for old _TEXT to get
a slightly less complicated memory model from the C compiler's
point of view.
* add support for int2f/4a01,4a02: query/allocate HMA space.
+ Changes Arkady V. Belousov
* slightly improved asm for print_hex and int2f clear_ax stuff
* use #error for unknown compilers
* remove hexDigits reference
* correct comment in kernel.asm (pad to 05fdh)
+ Changes Bart
* fix ss:sp init bug for int21/ax=4b01 (visible in DEBUG)
* fix redirection problem for character output routines
* fix press the any key message for floppy swaps
* correct cluster value for BAD cluster
* correct FAT12/16/32 cutoff magic values as per the MS spec
* the BUFFERS structure is now the same as in MSDOS 5+ and uses
a circular double-linked list using near pointers.
* move all old RCS log messages into one seperate file
* divide the fnode f_cluster_offset field by the size of a cluster:
this gives a more efficient map_cluster().
* point the CharMapSrvc pointer to the DOS DS for AARD compliance.
* nls.c: set CX to cooperate with load_unf.exe
2002 Nov 9 - Build 2027

Changed so if no source given or only source drive (no path)
given, then checks for kernel.sys & command.com in current
path (of current drive or given drive) and if not there
uses root (but only if source & destination drive are different).
Fix printf to include count(ret) if copy can't write all requested bytes

modified so takes optional 2nd parameter (similar to PC DOS)
where if only 1 argument is given, assume to be destination drive,
but if two arguments given, 1st is source (drive and/or path)
and second is destination drive

/* Revision 2.0 tomehlert 2001/4/26
no direct access to the disk any more, this is FORMAT's job
no floppy.asm anymore, no segmentation problems.
no access to partition tables
instead copy boot sector using int25/int26 = absdiskread()/write
if xxDOS is able to handle the disk, SYS should work
additionally some space savers:
replaced fopen() by open()
included (slighly modified) PRF.c from kernel
size is no ~7500 byte vs. ~13690 before
