[comp.sys.ibm.pc.hardware] Headland Technologies RAM controller / shadow RAM

v393vlqr@ubvmsd.cc.buffalo.edu (Daniel W Emmer) (05/11/91)

Anyone have details on how to access the memory management functions on a
Headland HT-12 chip?  The chip supports some variety of shadow RAM, but I 
don't know how to force it to shadow my hard disk controller ROM (the AMI BIOS
CMOS setup only allows for main and video BIOS shadowing) or make any of the
unused RAM reserved for shadowing (384K total) available for any other
purposes.  The chip is apparently incompatible with the C&T variety, which
makes all of the utilities I've tried so far useless....  The chip is also
supposed to provide LIM EMS 4.0 support, but no EMS driver was provided with
the motherboard and my other drivers don't seem compatible.
