Dell WorkStation 210 manual Lvnhwwh, 6SHDNHU

As part of the boot routine, the system first checks for a primary hard-disk drive con- troller card installed in an expansion slot. If no card is found, the integrated EIDE interface is enabled and the controller on the master EIDE drive is designated as the primary controller, using IRQ14. If any EIDE drives are attached to the secondary EIDE channel, IRQ15 is also used.

If a primary controller is detected on the expansion bus, the integrated EIDE interface is disabled.

Selecting Off disables the integrated EIDE interface.

Diskette controls the operation of the system’s integrated diskette drive controller.

With Auto (the default) selected, the system turns off the integrated diskette drive controller as necessary to accommodate a controller card installed in an expansion slot.

With Write-Protectselected, nothing can be written to diskette drives using the sys- tem’s integrated diskette drive controller. (The system can still read from the drives.) When Write-Protectis selected, the Auto setting is also in effect (the system turns off the integrated diskette drive controller as necessary).

Selecting Off turns off the integrated diskette drive controller; this setting is used primarily for troubleshooting purposes.
