EB3486-TN v Initial Setup Program After you power up your system, the BIOS message will appear on your screen and the memory count begins. After the memory test, the message below will appear on the screen if your CMOS setup is correct: Enter CURRENT Password: The default password is AMI.
PUMA Station Board AMI BIOS Setup Utilities If you want to change your CMOS setup, or your CMOS setup is incorrect, press <Del> when the mes- sage, "Hit <Del> if you want to run setup," appears on the screen. Again, if you enabled the password option, you will be prompted to the message below: Enter CURRENT Password: The default password is AMI.
EB3486-TN Standard CMOS Setup Before accessing this option, the warning message below will appear on the screen: This message warns you that if inappropriate modi- fications are made to the CMOS Setup, problems will occur. Press <Enter> to continue or press <Esc> to abort.
Page 36
PUMA Station Board The upper right hand corner shows the base memory size and extended memory size of your system. You cannot alter these items, as your computer automatically detects and displays them. The left side of the screen lists the modifiable parameters. You can change the date, time, hard disk drive (C and D) type, type of floppy drive (A and B), primary display, and keyboard options.
If you have added a hard drive, you must select the appropriate drive type for the drive. The EB3486-TN has 46 pre-set types and one user-definable type. The table in appendix G gives a complete listing of the available drive types.
Page 38
PUMA Station Board This message warns you that if inappropriate modi- fications are made to the Advanced CMOS Setup, problems will occur. Press <Enter> to continue or press <Esc> to abort. Note: If your system fails after the setup procedure, power off your system and turn it on again.
Page 39
EB3486-TN Note: The VL-Bus Adapter must be set to "Present" if there is any local bus device installed. The Memory Write buffer must be set to disable if any problem occurs on the VL-Bus Adapter. If memory write buffer is enabled, some VL-Bus adapters can gain much performance benefit from it.
PUMA Station Board The Boot Sector Virus Protection option may be set to "enabled" or "disabled". When enabled, the BIOS issues a warning when any program or virus sends a Disk For- mat command or attempts to write to the boot sector of the hard disk drive.
EB3486-TN Auto Configuration with Power-on Defaults The Power-on defaults are similar to the BIOS Setup defaults. These defaults are the most stable values for the system and should be used if you are having possible hardware problems. Highlight this option on the main menu and press <En- ter>.
