[. . . ] 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 640 K, 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 K 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 K to 1024 K address space. This is memory that can be used for different applications. DOS uses this area to load device drivers to keep 4-8 BIOS Configuration 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 No warning message to appear when anything attempts to Disabled 4-9 GA-586ATV access the boot sector or hard disk partition table · CPU Internal Cache / External Cache These two categories speed up memory access. However, it depends on CPU / chipset design. Enabled Disabled Enable cache Disable cache · Quick Power On Self Test This category speeds up Power On Self Test (POST) after you power on the computer. If it is set to Enable, BIOS will shorten or skip some check items during POST. Enabled Disabled Enable quick POST Normal POST · Boot Sequence This category determines which drive computer searches first for the disk operating system (i. e. , DOS). X1, X2, X3 System will first search for X1 disk drive then X2 disk drive and then X3 disk drive. · Swap Floppy Drive The default value is Disabled. Enabled Disabled Floppy A & B will be swapped under DOS Floppy A & B will be normal definition · Boot Up Floppy Seek During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360 K type is 40 tracks while 720 K, 1. 2 M and 1. 44 M are all 80 tracks. [. . . ] Write all CMOS values back to RAM and clear screen. Initialize any option ROMs present from C8000h to EFFFFh.
