[. . . ] R The Soul Of Computer Technology Mainboard SL-75DRV4 User Manual V2. 0 NOTICE Product Model Manual Revision Release Date : SL-75DRV4 : V2. 0 : March 2002 his Users Guide & Technical Reference is to help system manufacturers and end-users set up and install the mainboard. Every effort has been made to ensure that the information in this manual is accurate. is not responsible for printing or clerical errors.

Keep in mind that this feature protects only the boot sector, not the entire hard drive. NOTE: Many disk diagnostic programs that access the boot sector table can trigger the virus warning message. If you plan to run such a program, we recommend that you disable the virus warning. CPU Internal Cache/ Cache memory is additional memory that is much External Cache faster than conventional DRAM (system memory). CPUs from 486-type up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for faster access by the CPU. CPU L2 Cache ECC When you select Enabled, it will speed up memory Checking checking when the external cache contains ECC SRAMs. 58 Chapter 4 BIOS Setup Quick Power On Self Select Enabled to reduce the amount of time required to Test run the power-on self-test (POST). We recommend that you normally enable quick POST. First/Second/Third/ The BIOS attempts to load the operating system from Other Boot Device the devices in the sequence selected in these items. The choices: Floppy; LS/ZIP; HDD; SCSI; CDROM; Disabled. Swap Floppy Drive When enabled, floppy drives A and B will be exchanging without any physical connection and modification on the cables. Boot Up Floppy Seek When enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 270KB, 1. 2MB, and 1. 44MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives, we recommend that you set this field to a disabled to save time. Boot Up NumLock Toggle between On or Off to control the state of Status the NumLock key when the system boots. If On, the numeric keypad is in numeric mode. If off, the numeric keypad is in cursor control mode. Gate A20 Option Gate A20 refers to the way the system addresses memory above 1 MB (extended memory). When set to Fast, the system chipset controls Gate A20. When set to Normal, a pin in the keyboard controller controls Gate A20. Setting Gate A20 to Fast improves system speed, particularly with OS/2 and Windows. 59 75DRV4 Typematic Rate Setting When Disabled, the following two items (Typematic Rate and Typematic Delay) are irrelevant. Keystroke repeats at a rate determined by the keyboard controller in your system. When Enabled, you can select a typematic rate and typematic delay. Typematic Rate (Chars When the typematic rate setting is enabled, you can / Sec) select a typematic rate (the rate at which character repeats when you hold down a key) of 6, 8, 10, 12, 15, 20, 24, or 30 characters per second. Typematic Delay Choices: 250; 500; 750; 1000. This option sets the (Msec) time interval for displaying the first and the second characters. If enabled, the time interval is optional. Security Option If you have set a password, select whether the password is required every time the System boots, or only when you enter setup. The choices: system; setup. OS Select For DRAM > Select OS2 only if you are running OS/2 operating 64MB system with greater than 64MB of RAM on your system. Video BIOS Shadow Performance will be improved by copying Video BIOS to Shadow RAM. 3. Press <ESC> to return to the Main Menu when you finish setting up all items. 60 Chapter 4 BIOS Setup 4-6. 4 Advanced Chipset Features · Advanced Chipset Features is used to modify the values of chipset buffers. [. . . ] That is why it is called Single In Line. SIMM is made of FPM or EDO DRAM and supports 32-bit data. SIMM is phased out in current mainboard design. SPD (Serial Presence Detect) SPD is a small ROM or EEPROM device resided on the DIMM or RIMM. [. . . ]
