The above file will also be posted on: CompuServe Go ASTSUPPORT AST Worldwide Web Site Release 2.02 contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Built-in parallel port type changed from standard or enhanced to ECP mode. System halted with a 5Bh error code if two drives from different manufacturers were connected to the same IDE channel. Any add-in device using IRQ 15. Mouse enable problem when running Intel ICU. ENHANCEMENTS Added the ability to set each of the built-in serial ports to COM1 through COM4. Modified APM to report the battery status as not present instead of unknown. Production Release: 2.01 Available: July, 1995 Release 2.01 contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Corrected problem where more than 64MB of system memory causes a resource conflict with PCI cards requesting memory. Corrected a problem where INT-14 function requests with ranges greater than 5 would cause certain programs to require a cntrl-break to continue execution. Corrected ISA VGA add-in card failure. ENHANCEMENTS Added PnP OS option to System Setup. Production Release: 2.0 Available: May, 1995 Release 2.0 contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Corrected problem with PCI IDE device being enabled incorrectly. Fixed the problem that was causing IDE CD-ROMs to not show up on the secondary IDE controller under Windows 95. Fixed a problem that was causing apparent conflicts between the PCI IDE controller's secondary channel and the ISA secondary IDE controller under Windows 95. Fixed the problem that was causing the APM call to get the video status (function 0Ch) to hang the system. Fixed the problem that was causing the system to hang if the shadow memory test fails. Fixed IDE Mode 3 timing which effects CD-ROM drives. Fixed disk mode changes between 16-bit and 32-bit which were not working correctly when using the "SETIDE" program. Fixed problem with Option ROMs causing a system to crash due to low memory being corrupted during system POST. Fixed problem with WD 7197 SCSI controller not working during a warm boot. Fixed a problem where PCI VGA cards behind a PCI to PCI bridge are not recognized. Fixed a problem with the CMD640 IDE controller and its resources not appearing in ICU. Corrected problems with bus master devices behind a PCI to PCI bridge on warm boots. ENHANCEMENTS Added flash PID (Personality ID) which is now checked during POST for validity. Added virus scan capability at bootup time. Added support for PCI to PCI bridges. Added support for Interrupt 15, functions E801 HEX and E820 HEX added to BIOS to report Memory above ISA 64 MB limit. Production Release: 1.08 Available: February, 1995 This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Corrected problem with PCI IDE device being enabled incorrectly. ENHANCEMENTS Added Virus Scan capability at Bootup Time. Production Release: 1.07 Available: March, 1995 Revision: A This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Plug-n-Play bug fixes for Windows-95 LOGO requirements. APM no longer uses Hard disk, Serial or Parallel ports to activate screen monitor during standby. PCI IDE now seen by ISACU and resources are identified. ENHANCEMENTS Addition of Mode-4 Hard Disk support. Updated VGA driver. Production Release: 1.06 Available: February, 1995 Revision: A This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Corrected keyboard lock on key upon boot-up. Corrected user-defined Drive parameters option in System Setup. Corrected 3 Mode Floppy operation. Corrected resource locking utility in the ICU program. Production Release: 1.05 Available: February, 1995 Revision: A This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED When installing Windows applications from diskettes, the diskettes may not compress completely. When installing ODT SCO UNIX 3.0, the IDE hard drive scan would lock up with ISA SCSI adapter. Corrected IDE Hard Disk instability problems. Corrected APM mode switching problem. Corrected hard disk time-out problem when "Time-out" feature is enabled in system setup. Corrected problem in system setup mode due to insufficient stack space. Corrected a problem where some PCI Bus-Master cards prevented a Warm-Boot. Corrected Windows-95 protected mode crashes when accessing Plug-n-Play code. Corrected Date corruption when System Time is updated. BIOS updated to support P-n-P/PCI R1.21 runtime code. Production Release: 1.04 Available: December, 1994 Revision: A This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Correction to memory timing to fix memory errors on bootup. Correction for adapter cards with ROMS failing during bootup. Correction for shared IRQs causing errors during bootup. Failed Memory SIMM now properly identified during memory testing. ENHANCEMENTS VGA BIOS updated for Color monitors showing Monochrome only. Zero K Cache now supported. Production Release: 1.03 Available: November, 1994 Revision: A This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED Hard disk read errors on some systems. The read ahead feature of the primary hard disk controller is turned on to reduce the likelihood of encountering Read errors.
