Time Insert Wait

The DRAM time insert wait: RAS Active and CAS Precharge function setting.

Memory Write Insert Wait

ISA bus memory write insert wait

ISA High Speed

The Speed field shows the speed at which the processor runs internally.

I/O Recovery

If I/O Recovery Feature options is enabled, the BIOS inserts a delay time between two I/O commands. The delay time is defined in I/O Recovery Period option.

Memory Hole at 15-16 M

This option specifies the range 15MB to 16MB in memory that cannot be addressed on the ISA bus.

ISA I/O Recovery

ISA I/O Recovery Time

These options specify the length of the delay (in BUSCLK) inserted between consecutive 8-bit/16-bit I/O operations.

7.5 PASSWORD SETTING

This BIOS Setup has an optional password feature. The system can be configured so that all users must enter a password every time the system boots or when BIOS Setup is executed. User can set either a Supervisor password or a User password.

7.5.1 Setting Password

Select the appropriate password icon (Supervisor or User) from the Security section of the BIOS Setup main menu. Enter the password and press [Enter]. The screen does not display the characters entered. After the new password is entered, retype the new password as prompted and press [Enter].

If the password confirmation is incorrect, an error message appears. If the new password is entered without error, press [Esc] to return to the BIOS Main Menu. The password is stored in CMOS RAM after BIOS completes. The next time the system boots, you are prompted for the password function is present and is enabled.

Enter new supervisor password:

7.5.2 Password Checking

The password check option is enabled in Advanced Setup by choosing either Always (the password prompt appears every time the system is powered on) or Setup (the password prompt appears only when BIOS is run). The password is stored in CMOS RAM. User can enter a password by typing on the keyboard. As user select Supervisor or User. The BIOS prompts for a password, user must set the Supervisor password before user can set the User password. Enter 1-6 character as password. The password does not appear on the screen when typed. Make sure you write it down.

7.6 LOAD DEFAULT SETTING

In this section permit user to select a group of setting for all BIOS Setup options. Not only can you use these items to quickly set system configuration parameters, you can choose a group of settings that have a better chance of working when the system is having configuration related problems.

7.6.1 Auto Configuration with Optimal Setting

User can load the optimal default settings for the BIOS. The Optimal default settings are best-case values that should optimize system performance. If CMOS RAM is corrupted, the optimal settings are loaded automatically.
