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. SEE ECN No: EQ386/20-003 (10/9/92).

SYSTEM SETUP SYSTEM SETUP

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 NO: PROG4-002) 12/03/93.

Three text modes 62h,64h and 65h 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 predefined 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. 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 NO: PROG4002) 12/03/93.
