924f6d1bfd In case of "not sure" if the removable media has changed, the 
IBM PCDOS technical reference says to call BLDBPB if there are no used
buffers, so we only do it then, instead of flushing the buffers.

3e1c1a526f AllocateHMASpace needs to check FP_SEG(firstbuf) for 0xffff, since the 
buffers may not live in the HMA.

ab21f9be76 buffer intersection check should use > instead of >= (spotted by Arkady) 
small optimization -- the segment in bp == firstbuf is always the same
so we just need to compare offsets.

0e0abcd685 Added explicit (UWORD) type casts to avoid compiler warnings and sometimes 
save a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of bytes to
be added to SI.

bdc5569995 Set the Critical Error number immediately after calling a device driver. 
This solves problems with int24 handlers that call int21/ah=59.
Let truename and blockrw return with an error if there is a critical error.
Don't overwrite the critical error # with the DOS error #.

7c241c59c6 Always use huge block sectors if the relevant bit is set in the device 
header. This solves a problem with xmsdsk.

756c578ca7 (joint with Luchezar Georgiev): add extra low disk buffer to avoid HMA 
problems with certain device driver. Add an extra space for the device
driver command line and point to a correct environment for
INSTALL= (fixes problems with xmsdsk).
