Page 10: Hard Drives
Cable Select The Compaq Deskpro 4000 Series of Personal Computers use cable-select technology for identifying Device 0 (primary) and Device 1 (secondary) IDE hard drives. Check that the jumpers on the IDE hard drives are set properly for cable-select installation. Always check the label on the drives or check Chapter 7 of this manual when a new drive is added to verify that the jumper settings are set correctly. -

Page 12: Guidelines For Installing Optional Scsi Devices
All SCSI hard drives must be either internal or external, but never both. The system does accommodate a combination of other internal and external SCSI devices, such as SCSI tape and CD-ROM drives. Compaq Deskpro 4000 and 6000 Series of Personal Computers... - Page 13 Termination 1. Every SCSI chain must be terminated at both ends regardless of whether it is an internal SCSI chain, an external SCSI chain, or a combination internal-external SCSI chain. 2. Compaq SCSI-2 controllers have an automatic terminating device which turns OFF the terminator when both the external and internal SCSI signal ports connect to SCSI devices.

- Page 17 The supported memory configurations using x8 and x32 DIMMS are shown in Table E-2. Configuration # With a x32 in DIMM Slot 3, a x8 is not supported in either DIMM Slots 1 or 2. All other combinations of DIMM Modules (with the exception of the x4’s) are supported. If an unsupported configuration is found, the solution is to simply move the DIMM Modules into a supported configuration.
