[. . . ] When this feature is enabled, if there is any attempt from a software or an application to access the boot sector or the partition table, the BIOS will warn you that a boot virus is attempting to access to the hard disk. Introduction of BIOS 3-13 CPU Internal Cache: This item is used to Enable or to Disable the CPU internal cache. When the cache is set at Disable, it is much slower, so the default setting for this item is Enable. Some old and very bad programs will make the computer malfunction or crash if the system speed is to high. In that case, you should Disable this feature. CPU External Cache: This item is used to enable or to disable the CPU external cache. When the external cache is enabled, the system works faster. The default is Enable. Quick power on self test: After the computer has been powered on, the BIOS of the mainboard will run a series of tests in order to check the system and its peripherals. If the Quick power on self test feature is Enable, the BIOS will simplify the test procedures in order to speed up the boot process. The default is Enable. Boot Sequence: When the computer boots up, it can load the operating system from floppy drive A:, hard disk drive C:, SCSI disk drive or CD-ROM. There are many options for the boot sequence: OE A, C, SCSI · C, A, SCSI Z C, CD-ROM, A · CD-ROM, C, A · D, A, SCSI (at least 2 IDE HDD can be used) ` E, A, SCSI (at least 3 IDE HDD can be used) ' F, A, SCSI (at least 4 IDE HDD can be used) " SCSI, A, C " SCSI, C, A Swap Floppy Drive: This item can be set as Enable or Disable. When this feature is enabled, you don' need to open the computer t case to swap the position of floppy disk drive connectors. Drive A: can be set as drive B:, and drive B: can be set as drive A:. Boot Up Floppy Seek: When computer boots up, the BIOS detects if the system has FDD or 3-14 Chapter 3 not. When this item is enabled, if the BIOS detects no floppy drive, it will display a floppy disk drive error message. If this item is disabled, the BIOS will skip this test. Boot Up NumLock Status: ä On: At boot up, the Numeric Keypad is in numeric mode. ä Off: At boot up, the Numeric Keypad is in cursor control mode. IDE HDD Block Mode: This item can be set as Enable or Disable. Most of new hard disk drives (IDE drives) support multi-sector transfers. This feature speeds up hard disk drive access performance and reduces the time necessary to access data. When this item is enabled, the BIOS will automatically detect if your hard disk drive supports this feature or not, and will choose the right settings for you. 2 For further details about hard disk drive installation, refer to appendix E. Typematic Rate Setting: This item allows you to adjust the keystroke repeat rate. When enabled, you can set the two keyboard typematic control that follow (Typematic Rate and Typematic Rate Delay). If this item is disabled, the BIOS will use the default setting. Typematic Rate (Chars/Sec): When you press a key continuously, the keyboard will repeat the keystroke according to the rate you have set. (Unit: characters/second¡ ^ Typematic Rate Delay (Msec): When you press a key continuously, if you exceed the delay you have set here, the keyboard will automatically repeat the keystroke according a certain rate. (Unit: milliseconds) Introduction of BIOS 3-15 Security Option: This option can be set to System or to Setup. After you have created a password through PASSWORD SETTING, this option will deny access to your system (System) or modification of computer setup (BIOS Setup) by unauthorized users. [. . . ] OS/APPLICATION: Indicate what are the operating system and the applications your are running on the system. Example: MS-DOS 6. 22, Windows 3. 1. . . . *6. CPU: Indicate the brand and the speed (MHz) of your CPU. Example: (A) In the "Brand" space, write "Intel", in the "Specifications" space, write "150MHz"¡ C (B) In the "Brand" space, write "Cyrix", in the "Specifications" space, write "P166+"¡ C (C) In the "Brand" space, write "AMD", in the "Specifications" space, write "P75". 7. HDD: Indicate the brand and specifications of your HDD(s), specify if the HDD is using ¨IDE1 or ¨IDE2. [. . . ]
