LOC REASON
U1 INITIAL RELEASE
U113
U1 Three text modes 62h,64h and 65h
U113 have been restored. Incorporated new
VGA BIOS (v1.10.03) which changed
mode 072h (1024X768X4) back to
interlaced. Fixed problem between
EMM386.EXE and User defined HDD
parameter tables from the BIOS
extended data area into the shadow
RAM. Fixes problem where User
Defined HDD table different from pre-
defined HDD for the same drive by
one cylinder. Fixed problem in pre-
defined HDD tables where control byte
was not properly set for some drives
with more than 8 heads. Added
WD1170 HDD in the pre-defined HDD
table as type 30. (SEE ECN NO:
ENDVWG-001) 08/06/93.
U1 Corrected jagged cursor display in
U113 interlaced mode with the BT-482
RAMDAC when using the hardware
cursor Wingine display drivers. Serial
BIOS has been expanded to support
COM3 and COM4. Parallel BIOS has
been corrected to provide support for
LPT1-LPT3. Corrected inability to run
SETUP when an adaptec AHA-1540C
or 1542C SCSI host adapter is
installed by modifying POD to run
external ROM initialization routines
just prior to invocation of SETUP.
Corrected timing of parallel port
STROBE signal to allow for slow rise
time and longer cable lengths.
Removed internal cache test. The
cache test failed, regardless of cache
condition. Since the 80486 CPU
perform internal cache testing at
power-up, disabling the POD cache
test will not affect system
performance. (SEE ECN NO:
PROG4-002) 12/03/93.
