- WHAT'S NEW IN VERSION 1.15
- --------------------------
-
- - A new program (CHIPSET.EXE) that tests for the presence of one of
- the memory controller chips required in order to be able to use
- LASTBYTE.
-
- - LASTBYTE now supports the VLSI Technology VL82C202 memory
- controller chip (popular on 286 motherboards) as well as the
- following additional Chips and Technologies memory controllers:
-
- 82C222 - From the CHIPS/250 PS/2 50/60 chipset (286)
- 82C235 - The SCAT (tm) Single Chip AT VLSI chip (286)
- 82C241 - From the CS8223 LeAPset (tm) chipset (286)
- 82C311 - From the CS8233 PEAK 386/AT CHIPSet (tm) (386)
- 82C322 - From the CHIPS/280 PS/2 70/80 chipset (386)
- 82C841 - From the CS8283 LeAPset-sx (tm) chipset (386sx)
-
- ╔═══════════════════════════════════════════════════════════════╗
- ║ NOTE: We don't have access to the proper hardware to actually ║
- ║ test LASTBYTE on these products. We're confident it will ║
- ║ work with the LEAP and LEAPsx chipsets because these are NEAT ║
- ║ chipset compatible. If you have a machine with any of the ║
- ║ others, please let us know how it works (or doesn't). ║
- ╚═══════════════════════════════════════════════════════════════╝
-
- - Site licensing is now available with discounted pricing for orders
- of 10 copies or more. See LICENSE.DOC for details.
-
- - If the "?" option is used on the LASTBYTE.SYS command line, the screen
- is erased before the summary is displayed and a two second pause is
- inserted to give the user a chance to view the information. No erasure
- or pause occurs when the "?" option is not used.
-
- - The "?" output screen of LASTBYTE now displays the bus width (in
- bits) and bandwidth (speed) in megabytes per second of all memory
- found, as well as cpu type, cache controller type (if any), and
- memory controller type.
-
- ╔═══════════════════════════════════════════════════════════════╗
- ║ NOTE: The bandwidth computation is currently incorrect. It ║
- ║ is way too low, and will be corrected in a future release. ║
- ╚═══════════════════════════════════════════════════════════════╝
-
- - The output of HIGHMEM now indicates the bus width in bits, as in
- "16-bit VGA Disp Ram".
-
- - Corrected a problem in the high memory allocation routine shared by
- HIGHDISK, HIGHEMS3, and HIGHEMS4 that would cause them to hang for
- certain values of command line parameters.
-
- - Modified HIGHMEM to accept "-P" as well as "/P" to enable Paged
- Output; Corrected a minor bug in paging algorithm.
-
- - Improved the hardware signature computation to be more reliable.
-
- - Output listing invoked by LASTBYTE.SYS command line option "?" is now
- sorted by address.
-
- - Added "Shadow" option to LASTBYTE.SYS command line to force shadowing
- of ROM's not copied to shadow ROM by either the BIOS or LASTBYTE.SYS.
-
- - HIGHUMM.SYS API: Functions 8 and 9 now require a 6-byte save area
- rather than a 5-byte save area.
-
- - HIGHUMM.SYS can now be used as a "UMB-Only" XMS device driver without
- the need to first load HIMEM.SYS.
-
- - Phoenix BIOS (like AMI BIOS) seems to support use of the LASTBYTE
- DOS=F000:32 command line option!
-
- - LASTBYTE now supports Extended ROM bios (128K ROM).
-
- - LASTBYTE now recognizes all of the following as command line
- options that force it to assume a particular memory controller
- chip: 82C202, 82C212, 82C222, 82C235, 82C241, 82C302, 82C307,
- 82C311, 82C322, 82C812, 82C841.
-
- - HIGHBFRS now defaults to maximizing the number of buffers, and to
- automatically determining the safest location for loading the DOS
- buffers into high memory by sensing the presence of 16-bit adapter
- cards. A "SENSE" command line option has been added to force this
- condition.
