Choose these icons to configure the hard disk drive named in the option. When you click on an icon, the following parameters are listed: Type, LBA/Large Mode, Block Mode, 32Bit Mode, and PIO Mode. All parameters relate to IDE drives except Type.

Configuring an MFM Drive If configuring an old MFM hard disk drive, you must know the drive parameters (number of heads, number of cylinders, number of sectors, the starting write precompensation cylinder, and drive capacity). Choose Type and choose the appropriate hard disk drive type (1 - 46). The old MFM hard drive types are listed on page 82. If the drive parameters of your MFM drive do not match any drive type listed on page 82, select User in the Type field and enter the drive parameters on the screen that appears.

User-Defined Drive If you are configuring a SCSI drive or an MFM, RLL, ARLL, or ESDI drive with drive parameters that do not match drive types 1-46, you can select the User in the Type field. You must then enter the drive parameters on the screen that appears. The drive parameters include:

  • Cylinder (number of cylinders),

  • Hd (number of heads),

  • WP (starting write precompensation cylinder),

  • Sec (number of sectors),

  • Size (drive capacity).

Parameter Description
Type The number for a drive with certain identification parameters.
CylindersNumber of Cylinders The number of cylinders in the disk drive.
HeadsNumber of Heads The number of heads.
Write PrecompensationWrite Precompensation The size of a sector gets progressively smaller as the track diameter diminishes. Yet each sector must still hold 512 bytes. Write precompensation circuitry on the hard disk compensates for the physical difference in sector size by boosting the write current for sectors on inner tracks. This parameter is the track number where write precompensation begins.
Landing ZoneLanding Zone This number is the cylinder location where the heads will normally park when the system is shut down.
SectorsNumber of Sectors The number of sectors per track. MFM drives have 17 sectors per track. RLL drives have 26 sectors per track. ESDI drives have 34 sectors per track. SCSI and IDE drives have more sectors per track.
CapacityHard Disk Drive Capacity The formatted capacity of the drive is (Number of heads) x (Number of cylinders) x (Number of sectors per track) x (512 bytes per sector)

Configuring IDE Drives If the hard disk drive to be configured is an IDE drive, select the appropriate drive icon (Pri Master, Pri Slave, Sec Master, or Sec Slave). Select the IDE Detect icon to automatically detect all drive parameters.

AMIBIOS automatically detects the IDE drive parameters (including ATAPI CD-ROM drives) and displays them. Click on the OK button to accept these parameters Or you can set the parameters manually if you are absolutely certain that you know the correct IDE drive parameters.

Click on LBA/Large Mode and choose On to enable support for IDE drives with capacities greater than 528 MB.

Click on Block Mode and choose On to support IDE drives that use Block Mode.

Click on 32Bit Mode and click on On to support IDE drives that permit 32-bit accesses.

  • Anti-Virus (see page 101).

Two Levels of Passwords Both the Supervisor and the User icons configure password support. If you use both, the Supervisor password must be set first.

The system can be configured so that all users must enter a password every time the system boots or when WINBIOS Setup is executed, using either or both the Supervisor password or User password.

AMIBIOS Password Support

The Supervisor and User icons activate two different levels of password security.

If WINBIOS 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 WINBIOS Setup is executed.

Setting a Password

The password check option is enabled in Advanced Setup (see page Error! Bookmark not defined. by choosing either Always (the password prompt appears every time the system is powered on) or Setup (the password prompt appears only when WINBIOS is run). The password is encrypted and stored in NVRAM.

As shown on the above screen, you are prompted for a 1 - 6 character password. You can either type the password on the keyboard or select each letter of the password, one at a time, using the mouse. The password does not appear on the screen when typed. Make sure you write it down. If you forget it, you must drain NVRAM and reconfigure.

If You Do Not Want to Use a PasswordPress <Enter> when the password prompt appears.

Changing a Password

Select the Supervisor or User icon from the Security section of the WINBIOS 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>. The password is stored in NVRAM after WINBIOS completes. The next time the system boots, a password prompt appears if the password function is present and enabled.

Remember the Password Keep a record of the new password when the password is changed. If you forget the password, you must erase the system configuration information in NVRAM (Non-Volatile Random Access Memory). See page Error!

Original Choose the Original icon to return to the system configuration values present in WINBIOS Setup when you first began this WINBIOS Setup session.

Optimal You can load the optimal default settings for the WINBIOS by selecting the Optimal icon. The Optimal default settings are best-case values that should optimize system performance. If NVRAM is corrupted, the Optimal settings are loaded automatically.

Fail-Safe BIOS Setup Settings You can load the Fail-Safe WINBIOS Setup option settings by selecting the Fail-Safe icon from the Default section of the WINBIOS Setup main menu.

The Fail-Safe settings provide far from optimal system performance, but are the most stable settings. Use this option as a diagnostic aid if the system is behaving erratically.
