1.44MB 3.5" floppy drive as A: drive.
Requires CHET MAIN board revision
Y184201200 or above. See ECN
EQ386/20-002 (10/10/90).
Fixes problem with EMM386.SYS and
KEYB.COM. If 16MB of memory is
installed, and EMM386.SYS and
KEYB.COM are installed, CTRL-ALTDEL will hang the system. Fixes
problem with Imprimis 94244383,Conner CP344, CP3104 and
CP3204F. If two of these drives are
installed, and both are set to User
Defined Parameters, "1782- Disk
Controller Failure" is displayed often
during POD. The frequency of the
message depends on which two
drives are installed. Fixes problem
with Seagate ST-157A , when
attached to the IDE HDD controller,
the system cannot properly recognize
the HDD. Fixes "Shift Lock" problem
on keyboard. Intermittently, the
keyboard will go into a shift lock
mode. Fixes DECnet Scheduler
problem. After DECnet PCSA v3.0
or 3.1 is installed, various problem
occur when attached to DECnet.

shift key lock and/or keyboard lockup.
Fixes problem with Conner HDDs that
causes failure with INT 13h function
0bh, write sector long. To allow
CMOS to indicate daylight saving time
mode. To resolve incompatibility with
E1181A, T1183A, Seiko, Nec,
Capetronic and other monitors for
modes 60, 61, 62 and 64. Upgraded
to be compatible with VESA monitor
timing guideline. See ECN No:
EQ386/25+-003 (4/3/92).

Rapid keystrokes on all areas of the
keyboard may cause a shift key
lock and/or keyboard lockup. In
some rare cases, improper
keyboard timing may cause
intermittent system boot failure.

Corrected jagged cursor display in
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
