WHAT'S NEW IN VERSION 2.20
o CHIPSET.EXE: Reworked the user interface to accomodate the
addition of lots of new chipsets. Improved its ability to
continue where it left off when a test caused your PC to
hang.
o LASTBYTE.SYS, CHIPSET.EXE: Added support for the following
chipsets:
ACC Microelectronics: 2036, 2121, 2300
Addtech Research: "PC Chip"
(used on their motherboards M205,M209,M321)
Appian Technology: P915
Atmel Corporation: AT40281, AT40283, AT40391, AT40493
EFAR: 82EC495, 82EC798
ETEQ: ET82C390SX, ET391SX, ET6000, ET9000, ET9800
Chips & Technologies: 82C100, 84021
Forex: FRX46C411, FRX46C421
Mosel Corporation: MS400
Oak Technology: OTI-021, OTI-041
OPTi: 82C291, 82C295, 82C495SX, 82C498, 82C499, 82C683
PicoPower Technology: PT86C168, PT86C268
SiS: 85C360, 85C401, 85C411, 85C460
Symphony: SL82C471
UNIchip: U4800
Via Technologies: VT82C470, VT82C475, VT82C495
Victronix Technology: VIC92C4800
VLSI Technology: VL82C315, VL82C316
o LASTBYTE.SYS, HIGHAPND.SYS, HIGHAPND.EXE: Removed code in
LASTBYTE that intercepted video bios calls. This code was
only used by HIGHAPND; now this code is installed as a small
TSR in Hi-DOS memory the first time that HIGHAPND is
executed. The TSR can even be removed with HIGHUNDO provided
you have disabled the extension to conventional memory with
HIGHAPND OFF. Moving this code from LASTBYTE to the TSR
reduces the resident size of LASTBYTE.SYS, and thus reduces
the use of Hi-Dos memory for those users who do not use
HIGHAPND.
o LASTBYTE, CHIPSET, INSTALL, and HIGHMEM: Completely reworked
the use of color in the screens. This required elimination
of the TEXT option of LASTBYTE.SYS and eliminated the need
for the /LCD option of the utility programs.
o HIGHHOLE.EXE: Improved reporting format, and added entries
for the ROM character generator font tables.
o LASTBYTE.SYS: Now detects Cyrix 486SLC and 486DLC cpu chips.
WHAT'S NEW IN VERSION 2.20
o LASTBYTE.SYS: Now detects CPU cache as small as 1KB.
o LASTBYTE.SYS: Improved determination of cache Mbps.
o LASTBYTE.SYS: Modified the LIM4EMS and EEMS low-level
physical drivers so that the resident size of LASTBYTE.SYS is
reduced by approximately 40% when the NOEMS suboption is
used.
o LASTBYTE.SYS: Improved routine that verifies existence and
location of XBDA for the MOVE=XBDA option.
o LASTBYTE.SYS: Improved bandwidth calculations as displayed in
information screen.
o LASTBYTE.SYS: Corrected a problem with parsing of the
RESTRICT= and NAME= options. The first comma (if any) in the
parameter string and the rest of the text was being deleted.
o LASTBYTE.SYS: Corrected an initialization problem with the
low-level physical driver for LIM4EMS. When used with the
NOEMS suboption, it would sometimes hang, depending on who's
expanded memory device driver was being used.
o LASTBYTE.SYS: Corrected an initialization problem with the
low-level physical driver for VL82C202. The code that tested
whether or not the motherboard jumper that controls shadow
ram would hang due to a parity error if shadowing had not
been enabled in the CMOS setup.
o LASTBYTE.SYS: Corrected a problem with chipsets whose
configuration registers are write-only - i.e., the Texas
Instruments TACT82411 and all Suntac chipsets. Removed some
debugging code that had accidentally been left in the
released version.
o LASTBYTE.SYS: Eliminated a new feature introduced in version
2.11 that automatically made shadow ram available as
bank-switch memory (as opposed to being totally unavailable)
when it had been disabled by the presence of a real EMS
board. There are situations that disallow this, and which
cannot be distinguished via software; user can always use the
BankSwitch option of LASTBYTE.SYS.
o LASTBYTE.SYS: Corrected a problem with the "FRAME=" option in
the low-level drivers for the Headland HT12 and HT15
chipsets.
o CHIPSET.EXE: Corrected a problem with the detection of a
Headland HT113 chipset.
WHAT'S NEW IN VERSION 2.20
o LASTBYTE.SYS: Reduced the initialization time during
CONFIG.SYS processing.
