Release Note ==================== DIGITAL PC 3100 and Venturis FX-2 Series System BIOS Version : V1.12 Date : Feb 25 1999 BIOS.ROM - 256K BIOS image file for system rom flashed. PHLASH.EXE - flash rom utility, PLATFORM.BIN - flash rom utility. (used under DOS to flash) note: This PLATFORM.BIN file is only used under DOS to flash the system BIOS. It is different from the PLATFORM.BIN included in Crisis Recovery Disk which is used under "RECOVERY MODE".

The setup item under Main\IDE Adapter 0(1) Master(Slave) change to : (an example of a 14 G Hard disk) Autotype Fixed Disk: [Press Enter} CHS Format ------> new added Type: [Auto] 8455 Mb Cylinders: 17475 Heads: 15 Sectors/Track: 63 LBA Format ------> new added Maximum Capacity: 14453 Mb ------> new added Where 8455 Mb (8.4G) is the size of CHS format, and 14453 Mb (14 G) is the size of LBA format. The Hard disk sizes shown in both CHS and LBA format for some HDD size under 8.4G may have a +/- Mb difference. It is because of the calculation of size in CHS and LBA is different. ATTENTION: THE FOLLOWING CHANGES ARE IMPORTANT ATTENTION: Because the number of boot devices in SETUP is different, if the user downgrades the BIOS from version 1.11 to an older BIOS version, there is the possibility of the following happening: (a) In older BIOS versions, the text in SETUP/Boot MENU will appear different, for example: 1. Diskette 2. [Hard Drive] 3. Diskette --> not correct (b) The system can not boot from the boot devices For these two cases, the user can enter the SETUP/Exit MENU and select "Get Default Values" to get the setup default setting. Multi-Boot II Supporting description... In a MultiBoot system, the first boot device is selectable. It does not default to the Floppy device A: or IDE primary-Master. Any bootable device can be specified as a Master Boot device on the MultiBoot Menu of Setup. This allows you to select the order that boot devices are attempted. This feature is called the "Boot Priority" and is always present. If you select the [Hard Disk] item in the Boot Priority section of Setup and then press the key, the Boot Connection Device menu appears. The Boot Connection Device menu allows you to specify the order in which hard drives are installed into the system during ROM scan (POST code 98h). BOOT MENU: Some CD-ROM drives do not auto-type correctly. This will be apparent during POST when the "CD-ROM identified" message is not displayed. In this case, go into Setup and select the hard disk type for the CD-ROM manually, instead of auto-typing it in Setup. Many advanced operating systems such as Windows 95, Windows NT, OS/2 Warp, Unix, and others, modify the boot sectors of any hard drives that are installed in the system while the OS is being installed. This can cause normally bootable hard drives to be rendered non-bootable, even though the user did not want this behavior. In systems where there are two or more bootable hard drives, it is recommended that all bootable hard drives other than the target of the new OS be removed from the system prior to installing the new OS. Once installation of the new OS is complete, the other bootable drives can then be added back to the system. This simple procedure prevents the advanced Operating Systems from modifying the boot sectors of other bootable drives, thus preserving the MultiBoot II capability of choosing among several hard drives to boot from. Known Limitations: Support for 64Mbit DRAM technology: A. Memory SLOT 3 (J5) can not support a 64Mbyte DIMM using 64 Mbit DRAMs. 1. If any DIMM is installed in SLOT 3 (J5) then any 64Mbyte DIMM used in SLOT 1 (J7) or SLOT 2 (J6) will be identified as 16 Mbyte. 2. If slot 3 is empty then SLOT 1 and SLOT 2 can support 64 Mbyte DIMM using 64Mbit DRAMs. B. E-Segment is not free (BIOS version 1.02 does not use E-Segment) C. NT Power Panel can not "auto power off" the system when shut down.
