All hard drive configurations are a function of the System Configuration program (EISA Config).


Configuration - System Boards

In the Deskpro 386/33L and 486/33L, there are three jumpers on the system board.  They control:

Jumper	Pins	Function

E1	2 - 3*	Standard Configuration

E1	1 - 2	Erase Configuration

E2	2 - 3*	Enable Power-On Password

E2	1 - 2	Disable Power-On Password

E3	2 - 3*	Enable Integrated VGA

E3	1 - 2	Disable Integrated VGA

* Default

In the Deskpro 486/50L, SW500 on the system board controls:

1	2	3	4	5	6	Function

OFF	Reserved

OFF*	Unlock EISA Config

ON	Lock EISA Config

OFF*	Enable diskette write

ON	Disable diskette write

OFF*	Diskette drive as boot drive determined by EISA

config setting

ON	Enable diskette drive as boot drive regardless of

EISA configuration setting

OFF*	Enable user password protect

ON	Disable user password protection and remove old

password

OFF*	Enable EISA configuration

ON	Disable EISA configuration


Configuration - Video
