Release Note ==================== Venturis FX-2 Series System BIOS Version : V1.06 Date : AUG 22 1997 BIOS.ROM - 256K BIOS image file for system rom flash. 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".

Changed the text from "the Digiatl logo." to "the Digital logo." o Fixed the problem that Samsung SDRAM 64M DIMMs can not be detected in slot 0, and 128M DIMM can only be detected as 64M in slot 0 when using P54C 200MHz. o Fixed the problem that GoldStar 8X CD-ROM can not be reliably auto detected in setup or during warmboot. This problem happens only with this type of CD-ROM. o Implement a feature so that user can reserve free IRQs (3, 5, 9, 10, 11) which will not be assigned to PNP-ISA/PCI card by PNP BIOS during the POST. (1) Create a new setup item and five sub-item System IRQs Configuration: [Auto/Manual] IRQ9 reserved for Legacy ISA card [No/Yes] IRQ11 reserved for Legacy ISA card [No/Yes] IRQ10 reserved for Legacy ISA card [No/Yes] IRQ5 reserved for Legacy ISA card [No/Yes] IRQ3 reserved for Legacy ISA card [No/Yes] When 'AUTO' is selected, the five sub-item will be hidden. When 'Manual' is selected, the five sub-item will pop-up to user for selection. (2) Link the 'Plug & Play O/S' setup item with 'System IRQs Configuration' so that when set to 'Manual', the 'Plug & Play O/S' item will be hidden. The system will set PnP OS = 'No' when "Manual" is selected regardless of the actual setting of the 'Plug & Play O/S'. o Fixed the problem that when running the AMIdiag utility from diskette, the system will hang at "Device APM Test" (when run from the HDD, AMIdiag will PASS). o Fixed the problem that in Win95 the "Resume on Modem Ring" will fail to wake up the system when using the mouse to click the "suspend" icon. o Fixed a system hang problem that would occur during a data transfer on the Bus Master HDD when the NT power panel "maximum performance" icon was "clicked" 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: If is pressed during POST, a menu appears that allows you to over-ride the default boot order with a "Boot First" device selection. You can also enter CMOS Setup from this 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.
