[. . . ] GA - 586T2 USER'S MANUAL ¯ Auto detect CPU Voltage. ¯ Switching mode Voltage regulator on Board. ¯ Support Cyrix / IBM 6x86MX & AMD-K6 CPU. ¯ In CASE you want to Power OFF System Before Boot up please press Soft-Power more than 4Secs. [. . . ] Drive A & B are 3 mode Floppy Drive. · Video The category detects the type of adapter used for the primary system monitor that must matches your video display card and monitor. Although secondary monitors are supported, you do not have to select the type in setup. EGA/VGA CGA 40 CGA 80 MONO Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA, SVGA, or PGA monitor adapters Color Graphics Adapter, power up in 40 column mode Color Graphics Adapter, power up in 80 column mode Monochrome adapter, includes high resolution monochrome adapters 4-8 GA-586T2 · Halt on The category determines whether the computer will stop if an error is detected during power up. NO errors All errors All, But Keyboard All, But Diskette All, But Disk/Key The system boot will not be stopped for any error that may be detected Whenever the BIOS detects a non-fatal error the system will be stopped and you will be prompted The system boot will not stop for a keyboard error; it will stop for all other errors The system boot will not stop for a disk error; it will stop for all other errors The system boot will not stop for a keyboard or disk error; it will stop for all other errors · Memory The category is display-only which is determined by POST (Power On Self Test) of the BIOS. Base Memory The POST of the BIOS will determine the amount of base (or conventional) memory installed in the system. The value of the base memory is typically 512 K for systems with 512 K memory installed on the motherboard, or 640 K for systems with 640 K or more memory installed on the motherboard. Extended Memory The BIOS determines how much extended memory is present during the POST. This is the amount of memory located above 1 MB in the CPU's memory address map. Expanded Memory Expanded Memory in memory defined by the Lotus / Intel / Microsoft (LIM) standard as EMS. Many standard DOS applications can not utilize memory above 4-9 Bios Configuration 640, the Expanded Memory Specification (EMS) swaps memory which not utilized by DOS with a section, or frame, so these applications can access all of the system memory. Memory can be swapped by EMS is usually 64 within 1 MB or memory above 1 MB, depends on the chipset design. Expanded memory device driver is required to use memory as Expanded Memory. Other Memory This refers to the memory located in the 640 to 1024 address space. This is memory that can be used for different applications. DOS uses this area to load device drivers to keep as much base memory free for application programs. Most use for this area is Shadow RAM. 4. 6.

During and after the system boots up, any attempt to write to the boot sector or partition table of the hard disk drive will halt the system and the following error message will appear, in the mean time, you can run anti-virus program to locate the problem. Enabled Activate automatically when the system boots up causing a warning message to appear when anything attempts to access the boot sector or hard disk partition table. Disabled No warning message to appear when anything attempts to access the boot sector or hard disk partition table. · CPU Internal Cache / External Cache These two categories speed up memory access. [. . . ] Otherwise display any messages (i. e. , any non-fatal errors that were detected during POST) and enter Setup. Write all CMOS values back to RAM and clear screen. Initialize any option ROMs present from C8000h to EFFFFh. F When FSCAN option is enabled, will initialize from C8000h to F7FFFh. [. . . ]
