Hardware Description

The VXIpc 800 Series controllers feature a modular, PCI-based local bus design that makes it easy to use interchangeable daughterboards to upgrade your controller to new microprocessors, without having to replace the motherboard or enclosure.

The VXIpc 800 Series currently consists of two models—the VXIpc-850 and the VXIpc-860—which vary in p rocessors and sp eeds.

The CPU module and its memory sockets are easily accessible for you to install additional DRAM in the field:

• Up to 128 MB for the VXIpc-850

• Up to 256 MB for the VXIpc-860 The VXIpc 800 contains at least an 800 MB internal, enhanced IDE

hard disk. For information on adding RAM by installing SIMMs, refer to Appendix A,

Specifications

Slot 0 Functionality

You can use the VXIpc 800 Series computers to achieve full VXI Slot 0 control of your VXI system. You can also install the VXIpc 800 in another slot and use it in Non-Slot 0 mode. You do not have to change any switches or jumpers when moving between these two modes, as the VXIpc 800 can automatically detect whether it is installed in Slot 0 and it will automatically enable or disable the Slot 0 onboard circuitry.

VXIpc 800 Series User Manual 1-4 © National Instruments Corporation

Custom Application-Specific Interface Chips

The VXIpc 800 Series uses the MITE and MANTIS custom ASICs to deliver high VXI performance, and can achieve more than 20 MB/s DMA block-mode data transfer rates across the VXI backplane.

The VXIpc 800 Series has the TNT4882C custom ASIC to give full GPIB control of external instruments via a front-panel connector. GPIB capability is fully compatible with IEEE 488.2 and the industry-standard NI-488.2 driver for a variety of operating systems.

The MITE custom ASIC is a sophisticated dual-channel DMA controller with standard interfaces for VXI and PCI. By using MITE DMA to transfer data and commands to and from devices, the MITE frees the computer’s microprocessor to perform other tasks such as data analysis and presentation. In addition to DMA, the MITE incorporates the new VME64 MBLT (8-byte block transfers in which both the address bus and data bus are used to transfer data) directly into the ASIC to perform the fastest transfer operation to instruments. With the multiple windowing scheme of the MITE, you can easily access all of VXI address space.

The VXI trigger interface on the VXIpc 800 is based on the MANTIS custom ASIC. The VXIpc 800 front panel has two SMB trigger I/O connectors, which you can use to route any of the TTL trigger lines between the backplane and external devices. The MANTIS ASIC on the VXIpc 800 provides the complete VXI interface to the backplane connector in a single chip. The VXIpc 800 can respond to all VXI-defined protocols on all P2 TTL and ECL trigger lines at the same time. The MANTIS features an internal cross-matrix switching system for routing between lines as well as to and from the front panel and onboard clocks.

Chapter 1 Introduction

Note: The MANTIS ASIC contains the exact functionality of the TIC ASIC,

which appeared on the VXIpc-486 Model 500 Series controllers. Any application that currently uses any of the TIC functionality, such as the crosspoint switch and counter/timers, can run on a controller containing the MANTIS ASIC without modification.

Configuring the VXIpc 800 Series

This section describes how to configure the following options on the VXIpc-800:

• VXIbus Slot 0/Non-Slot 0

• VXIbus CLK10 routing

• Trigger input termination

• EEPROM

• Installed system RAM

How to Remove the Metal Enclosure

The VXIpc-800 is housed in a metal enclosure comprised of a top and bottom cover to improve EMC performance and to provide easy handling. You must remove the top cover to change many of t he switch and jumper settings. You must also remove the top cover to change the amount of DRAM installed on the module.

Remove the top cover by removing the 12 screws that attach it to the module.

VXIbus Slot 0/Non-Slot 0

The VXIpc-800 is configured at the factory to automatically detect if it is installed in Slot 0 of a VXIbus mainframe. With automatic Slot 0 detection, you can install the module into any VXIbus slot.

You can manually configure the VXIpc-800 for either Slot 0 or Non-Slot 0 operation by defeating the automatic-detection circuitry. Use the three-position jumper W13 to select automatic Slot 0 detection, Slot 0, or Non-Slot 0 operation. Figure 3-2 shows these three settings.

Caution: Do not install a device configured for Slot 0 into another slot without

VXIpc 800 Series User Manual 3-4 © National Instruments Corporation

first reconfiguring it to either Non-Slot 0 or automatic configuration. Neglecting to do this could result in damage to the device, the VXIbus backplane, or both.

Chapter 3 VXIpc 800 Series Configuration and Installation

When the VXIpc-800 is installed in Slot 0, it becomes the VXIbus System Controller. In this role, it has VXIbus Data Transfer Bus Arbiter circuitry that accepts bus requests on all four VXIbus request levels, prioritizes the requests, and grants the bus to the highest priority requester. As VXIbus System Controller, the VXIpc-800 also drives the 16 MHz VXIbus system clock by an onboard 16 MHz oscillator.

As required by the VXIbus specification, the VXIpc-800 drives the 10 MHz signal CLK10 on a differential ECL output when installed in Slot 0. When not installed in Slot 0, the VXIpc-800 only receives the CLK10 signal.

VXIbus CLK10 Routing

When the VXIpc-800 is installed in Slot 0 of your mainframe, it supplies the VXIbus CLK10 signal. The VXIpc-800 can use two different sources to generate this signal: an onboard oscillator, or the external CLK SMB connector. Use switch S3 to select these options, as shown in Figure 3-3.

The VXIpc-800 can also be configured to drive the external CLK SMB signal from the VXIbus CLK10 signal. Switch S5 controls whether the VXIpc-800 drives or receives the external CLK SMB signal. If you change the S5 setting to drive CLK10 out the external CLK10 SMB connector (Figure 3-4b), do not set S3 to source CLK10 to the backplane from the SMB; instead use the setting shown in Figure 3-3a.

When switch S5 is set so that the VXIpc-800 receives the SMB CLK10 signal, you have the option to add a 50 Ω termination to the signal by setting switch S6. Switch S6 is unused—its setting does not matter— when S5 is configured to drive the external CLK SMB signal. Figure 3-5 shows the settings for switch S6.

You can use switch S7 to terminate the external trigger input SMB with 50 Ω to ground. Figure 3-7a shows the default setting for a non-terminated trigger input SMB. Use the setting of Figure 3-7b to terminate the trigger input SMB. Switch S7 is located above switches S4, S5, and S6, which have no effect on this configuration.

The VXIpc-800 has an onboard EEPROM, which stores default register values for the VXI circuitry. These values are loaded when you power up the computer. These values read from the EEPROM tell the PCI interface of the VXIbus registers so that the VXI interface is ready to respond to Resource Manager accesses within the required 5 s of SYSRST* deasserting. You can use switch S2 to disable this power-on self-configuration (POSC) circuit. Although this makes the VXI circuitry unusable, it is sometimes helpful in debugging address and interrupt conflicts with add-in boards. In general, howev er, you should leave switch S2 in its factory-default setting. Figure 3-8 shows the possible configurations for S2.

Chapter 3 VXIpc 800 Series Configuration and Installation

The EEPROM is divided into two halves; one hal f is factory configured and one half is user configurable. Use switch S9 to control the operation of the EEPROM. The setting of this switch determines whether the VXIpc-800 boots off the factory-configured half or the user-modified settings. This is useful in the event that the user-configured half of the EEPROM becomes corrupted in such a way that the VXIpc-800 boots to an unusable state. In its default setting, the VXIpc-800 boots off the user-configurable half.

Figure 3-9 shows the configuration settings for EEPROM operation.

How to Fix an Invalid EEPROM Configuration

The NI-VXI software includes a configuration utility you can use to edit the configuration of the VXIpc-800. Use T&M Explorer under Windows 95/NT, or VXIedit for all other platforms. Some of these settings are stored in files that are read by the NI-VXI software, while other settings are stored directly in the VXIpc-800 EEPROM. Certain EEPROM configurations can lock up your PCI computer while it is booting up. Generally, only the size and location of the memory windows can cause your VXIpc-800 to lock up your system. For example, many PCI-based computers will not boot if a board in its system requests more memory space than the computer can allocate. If you encounter this situation you should reduce the size of the VXIpc-800 user window.

Chapter 3 VXIpc 800 Series Configuration and Installation

If this situation occurs after you change the configuration, perform the following steps to reconfigure the VXIpc-800.

1. Turn your computer off.

Warning: To protect both yourself and the mainframe from electrical hazards, the

mainframe should remain off until you are finished changing the settings on the VXIpc-800 module.

2. Change switch S9 to the OFF position as shown in Figure 3-9b to restore the factory configuration.

3. Turn on the computer. The computer should boot this time because the factory-default configuration is being used to initialize the VXIpc-800 module.

4. Run your software configuration utility to re-adjust the VXIpc-800 configuration.

5. After saving the configuration, exit Windows and turn off the computer.

6. Change switch S9 to the ON position, as shown in Figure 3-9a.

7. Turn on the computer. If the computer does not boot with this configuration, you will have to repeat these steps, modifying your configuration until a final configuration is reached.

Installed System RAM

The 16 MB of installed RAM is factory configured per customer order. You can change the amount of installed RAM on the VXIpc 800 Series by installing DRAM SIMMs. Refer to Appendix A, more information on SIMMs.

Installing the VXIpc 800 Series

This section contains general installation instructions for the VXIpc-800. Consult your VXIbus mainframe user manual or technical reference manual for specific instructions and warnings.

1. Plug in your mainframe before installing the VXIpc-800. The power cord grounds the mainframe and protects it from electrical damage while you are installing the module.

Warning: To protect both yourself and the mainframe from electrical hazards,

the mainframe should remain off until you are finished installing the VXIpc-800 module.

2. Remove or open any doors or covers blocking access to the mainframe slots.

3. If you are installing the VXIpc-800 into a D-size mainframe, install a support designed for installing C-size boards in D-size mainframes. The VXIpc-800 has no P3 connector and cannot provide P3 Slot 0 control to VXI devices requiring this capability.

b. Hardwired Ethernet Values

Caution: If the VXIpc-800 is not configured for automatic Slot 0 detection, be

certain that the slot you select in your VXIbus mainframe matches the VXIpc-800 configuration as either a Slot 0 device or a N on-Slot 0 device. If you install your VXIpc-800 into a slot that does not correspond with the jumper setting, you risk damage to the VXIpc-800, the VXIbus backplane, or both.

Chapter 3 VXIpc 800 Series Configuration and Installation

4. Insert the VXIpc-800 in the slot you have selected b y aligning the top and bottom of the module with the card-edge guides inside the mainframe. Slowly push the VXIpc-800 straight into the slot until its plug connectors are resting on the backplane receptacle connectors. Using slow, evenly distributed pressure, press the module straight in until it seats in the expansion slot. The front panel of the VXIpc-800 should be even with the front panel of the mainframe.

5. Tighten the retaining screws on the top and bottom edges of the front panel.

Note: The VXIpc-800 must be populated with pairs of SIMMs because the DRAM

interface is 64 bits wide.

VXIpc 800 Series

Appendix

System Resources

This appendix describes what system resources are available on the VXIpc 800 Series and where they are allocated. Because PCI is a relatively new addition to PCs, this appendix describes how PCI interrupts fit into a PC architecture before listing the devices that use them.

PCI Interrupts

PCI interrupts can be shared by multiple devices and are therefore more flexible than ISA interrupts. They do not actually connect to the processor directly; they are instead mapped through ISA interrupts in the system I/O module. The interrupt handler for a particular ISA interrupt must know if it will be acknowledging a PCI device.

Resource Tables

This section provides tables describing where system resources are assigned. Table B-1 lists how the ISA interrupts are allocated on the VXIpc 800 Series and whether they are driven by a PCI interrupt. Table B-2 lists DMA channel allocation, and Table B-3 gives the I/O address map.

LED Indicators

This appendix describes how to read the LEDs on the front panel to interpret the status of the VXIpc 800 Series.

VXIbus Interface Status LEDs

The VXIbus interface status LEDs are located at the top of the module and include four LEDs: They indicate the various stages of initialization that occur as the VXIpc 800 boots. The following paragraphs describe each LED.

If either the SYSFAIL or FAILED LED remains lit, perform the following steps.

1. Power off the mainframe.

2. Remove all other modules from the mainframe.

3. Make sure that the VXIpc 800 jumper settings are correct.

4. Make sure that the VXIpc 800 is seated properly in the mainframe.

5. Power on the mainframe and observe whether the SYSFAIL and FAILED LEDs become unlit some time before the operating system boots.

Board Access LEDs

The board access LEDs—ACCESS and DRIVE—indicate when board resources have been accessed. The following paragraphs describe these LEDs.

ACCESS LED

When lit, the ACCESS LED indicates that the VXIpc 800 MODID line is asserted or that another VXIbus master is accessing VXIbus shared registers or shared memory.

Appendix C LED Indicators

I/O Expansion Boards

This appendix explains how to modify and install an I/O board in the VXIpc 800 Series. Notice that some material is different between the VXIpc-850 and the VXIpc-860.

Height of VXIpc-850 Plug-In Boards

In general, the VXIpc-850 can accommodate any standard-size PCI card and any XT-height ISA card. The height of an I/O card is measured from the bottom of the bus connector to the top of the board, as shown in Figure E-1.

Height

(4.2 in. max)

(13.415 in. maximum when using .85 in. high SIMMs on processor board)

Both XT-height ISA cards and PCI cards are 4.2 in. high. The VXIpc-850 does not support AT-height ISA cards, which are 4.8 in. high.

Length

Figure E-1.

I/O Board Dimensions for VXIpc-850 Expansion Slot

Appendix E Modifying and Installing I/O Expansion Boards

Length of VXIpc-850 Plug-In Boards

The VXIpc-850 will accommodate PCI or ISA I/O boards that are up to

4.2 in. high and up to 13.415 in. long when DRAM SIMMs 0.85 in. or shorter are used on the processor board (National Instruments provides

0.85 in. SIMMs). Due to slight variances in I/O board geometries, however, take care in every application to identify possible contact with the SIMMs. The maximum recommended board length is 7.72 in. if you are using SIMMs taller than 0.85 in. If you want to install a longer board with taller system DRAM SIMMs, you must consider the strong possibility of contact with the SIMMs.

Because DRAM SIMMs taller than 0.85 in. are more likely to interfere with ISA cards than PCI cards, the two are discussed separately in the following sections.

Length of PCI Plug-In Boards

The VXIpc-850 accommodates any standard 32-bit, 5 V PCI I/O board . The maximum standard dimensions of a PCI I/O board are 12.283 in. by

4.2 in. PCI cards are installed in the VXIpc-850 such that the board components face the processor card, which contains the processor and system RAM. Exceptionally tall PCI components (higher than 0.52 in.) on a plug-in board may physically cont act the DRAM SIMMs inst alled on the CPU card, as shown in Figure E-2.

SIMMs

VXI Connector

Because larger DRAM sizes may employ taller SIMMs, you must be careful that the component height of the PCI board does not interfere with the SIMMs in such a way that electrical shorts occur or that the PCI board is stressed enough to compromise its physical or electrical integrity.

Length of ISA Plug-In Boards

Because ISA boards mount with the components facing away from the CPU card, which contains the processor and system RAM, tall DRAM SIMMs may interfere with the circuit card of the plug-in board. Most SIMM modules are at least 1 in. high and would extend into the ISA circuit card keepout area. Therefore, National Instruments provides SIMMs of 0.85 in. high, and does not recommend the use of cards that are longer than 7.72 in. if you choose to use taller SIMMs. They can be made to fit; however, take care to ensure the following conditions:

• Contact of the board with the SIMMs should not cause electrical shorts (because of through-hole component leads on the side of the plug in board that contacts the SIMMs).

• Contact of the board with the SIMMs does not cause physical stress to the plug-in board.

• Contact of the board with the SIMMs does not cause physical stress to the riser board into which the plug-in board is inserted.

Appendix E Modifying and Installing I/O Expansion Boards

Length of VXIpc-860 Plug-In Boards

The VXIpc-860 can accommodate PCI or ISA I/O boards that are up to

4.2 in. high and up to 8.4 in. long. When DRAM SIMMs 0.85 in. are used on the processor board, the component-side component height on a PCI I/O board shall be 0.48 in. tall in the area shown in Figure E-4. For the same height DRAM SIMMs, the ISA I/O board solder-side component height shall be 0.07 in. tall in the area shown in Figure E-4. Be sure to allow for clearance if you want to use taller DRAM SIMMs.

Because DRAM SIMMs taller than 0.85 in. are more likely to interfere with ISA cards than PCI cards, the two are discussed separately in the following sections.

Length of PCI Plug-In Boards

The VXIpc-860 accommodates any 32-bit, 5 V PCI I/O boards that are a maximum of 8.4 in. long with the standard height of 4.2 in. (see Figure E-5). PCI cards are installed in the VXIpc-860 such that the board components face the processor board, which contains the processor and system RAM. PCI components (higher than 0.48 in. in the area shown in Figure E-4) on a plug-in board may physically contact the DRAM SIMMs installed on the CPU card, as shown in Figure E-5.

Length of ISA Plug-In Boards

Because ISA boards mount with the components facing away from the CPU card, which contains the processor and system RAM, tall DRAM SIMMs may interfere with the circuit card of the plug-in board. Most SIMM modules are at least 1 in. high and would extend into the ISA circuit card. Therefore, National Instruments provides SIMMs of 0.85 in. high to give a clearance of 0.07 in. to the ISA circuit card only in the area shown in Figure E-4. If you choose to use taller SIMMs (0.92 maximum height), take care to ensure the following conditions:

• Contact of the board with the SIMMs should not cause electrical shorts (because of through-hole component leads on the side of the plug in board that contacts the SIMMs).

• Contact of the board with the SIMMs does not cause physical stress to the plug-in board.

• Contact of the board with the SIMMs does not cause physical stress to the riser board into which the plug-in board is inserted.

Installing an I/O Board

The following material applies equally to all models in the VXIpc 800 Series.

Materials Needed

You need the following pieces to install an expansion board in the VXIpc-800:

• A user-defined panel is required on the expansion boards based on National Instruments blank PCI or ISA panels. The panel should be manufactured from 0.03 in. (0.76 mm) thick 1010 cold rolled steel. The finish should be 0.0003 in. (0.008 mm) nickel plate over 0.0001 in. (0.003 mm) copper flash. Contact National Instruments if you have any questions about specifications for user-defined panels.

As an alternative, you can modify the blank panels provided with the VXIpc-800. Custom panel design services are available from National Instruments for a nominal fee.

• PEM nut or a 4-40 nut with lock washer (hole diameter should be 0.125 in. [3.18 mm]).

• 4-40 x 1/4 in. stainless steel panhead screw.

Appendix E Modifying and Installing I/O Expansion Boards

Installation Steps

Follow these steps to install the expansion board.

1. Notice that the VXIpc-800 includes one card guide that can be rotated to secure the top of either a PCI or an ISA plug-in board. You may use the card guide in either of two locations, depending on the length of your installed board. Notice the possible locations as shown previously (Figures E-2 and E-3 for the VXIpc-850, or Figures E-5 and E-6 for the VXIpc-860). Loosen the screw holding the guide and rotate the guide to the uppermost position for PCI boards or the lowermost position for ISA boards. See Figure E-7.

2. Replace the manufacturer-supplied panel bracket with the custom bracket. The two holes in the bracket align with existing holes in the VXIpc-800 front panel.

3. Seat the board firmly in one of the expansion bus connectors.

4. Attach the board to the front panel with the two screws. You can use a PEM nut on the back (far) side of the bracket, or a 4-40 nut

Appendix E Modifying and Installing I/O Expansion Boards

with a lock washer (hole diameter should be 0.125 in.). In either case, use a 4-40 x 1/4 in. stainless steel panhead screw to mount the board/bracket assembly to the front panel.

Appendix

Common Questions

This appendix answers common questions you may have when using the VXIpc 800 Series.

What do the LEDs on the front of the VXIpc 800 mean?

Refer to Appendix C , panel LEDs.

Is something wrong with the VXIpc 800 if the red SYSFAIL and FAILED LEDs stay lit after booting the VXIpc 800?

If either the Appendix C,

Can I access 32-bit registers in my VXIbus system from the VXIpc 800?

Yes. The VXIpc 800 uses the 32-bit PCI bus to interface to the VXIbus. In fact, the VXIbus circuitry on the VXIpc 800 also supports the new VME64 standard for D64 accesses. Refer to your VXI software manual for more information.

SYSFAIL

LED Indicators

FAILED

, for troubleshooting steps.

, for a description of the front

LED remains lit, refer to

What kind of signal is CLK10 and what kind of signal do I need for an external CLK10?

CLK10 is a differential ECL signal on the backplane. However, the oscillator for the VXIpc 800 and the EXTCLK i npu t on the VXIpc-8 00 front panel use TTL levels; therefore, you need to supply a TTL-level signal for EXTCLK. Our voltage converters convert the signal to differential ECL.

What is the accuracy of the CLK10 signal?

The CLK10 signal generated by the VXIpc 800 is ±100 ppm (0.01%) as per the VXIbus specification. If you need a more accurate CLK10 signal on the VXIpc 800 Series, you can use the EXTCLK connector on its front panel.

Appendix F Common Questions

If I boot the computer without video, and then plug in the video, why is it in black and white?

When the computer first boots, the video chips try to synchronize with the monitor. If the monitor is not there, the video chips cannot synchronize and establish color. You need to have the monitor at tached at boot time to get color.

I’ve installed the SCSI software. Why doesn’t the VXIpc 800 Series recognize my SCSI device?

This problem usually occurs when SCSI has not been enabled in the BIOS. Enter your BIOS by pressing <DEL> at boot time. In the Setup window, click on the Chipset icon. Select the On Board PCI SCSI option and enable it.

What type of video interface is onboard the VXIpc 800? What video drivers are included with the VXIpc 800? Can I use Super VGA with my VXIpc 800? If my application requires a special type of video display, how do I configure my VXIpc 800?

The VXIpc 800 uses the Trident Microsystems TGUI96xx chip family, a combination graphics accelerator and RAMDAC. The TGUI9660 is the first chip used from this family. Subsequent pin-compatible chips will follow. The chips in this family are compatible with the Standard VGA video output MS Windows video driver, as well as the Trident Microsystems video driver. For more information on the video driver, refer to the

c:\images\manuals directory.

If your application requires a special type of video display, you can remove the PCI video card included with your VXIpc 800 Series. Contact National Instruments for information on how to do this.

What kind of monitor can I use with the VXIpc 800?

VXIpc 800 computers that use Super VGA video output will work o nly with monitors having a horizontal scan rate of at least 50 kHz and a vertical scan rate of 60 Hz.

Caution: Make sure that your monitor meets this specification. Enabling the Super

VGA option on a monitor that does not meet this specification will cause damage to your monitor.

Appendix F Common Questions

What if my keyboard connector does not fit into the keyboard port on the VXIpc 800?

You can plug keyboards that have a 6-pin Mini DIN PS/2 type connector directly into the VXIpc 800. You can use the keyboard adapter cable that is included with every VXIpc 800 kit to adapt the larger AT keyboard connector to the 6-pin Mini DIN connector.

How do I connect an external speaker to get audio capability?

A twisted-pair cable connects th e front pane l audio co nnector to the VXIpc 800 Series motherboard. Connect the external speaker to this front-panel connector. The center pin of the connector provides the audio signal. The shield of the connector is GROUND.

How do I add RAM to the VXIpc 800? What is the maximum amount of RAM that I can have on the VXIpc 800?

For information about adding RAM to the VXIpc 800, refer to Appendix A,

Specifications

Which interrupt levels are free to be used by ISA bus boards? Which area of upper memory (adapter space) is free for use by ISA bus boards or expanded memory manager software programs?

See Appendix B,

VXIpc 800 Series System Resources,

for information on the available port I/O register space, upper memory area, interrupts, and DMA channels.

How do I install the VXIpc 800 in a slot other than Slot 0?

The VXIpc 800 automatically detects whether it is in Slot 0 of a VXIbus mainframe. You do not need to change jumper settings to install the VXIpc 800 in a slot other than Slot 0 unless you h av e defeated the first slot detector (FSD) circuitry by changing the appropriate jumper setting on the VXIpc 800.

Refer to either Chapter 3,

Installation

, for information on enabling and defeating the FSD

VXIpc 800 Series Configuration and

circuitry.

Appendix F Common Questions

How do I check the configuration of the memory, floppy drive, hard drive, time/date, and so on?

You can view these parameters in the BIOS setup. To enter the BIOS setup, reboot the VXIpc 800 and press the <DEL> key during the memory tests. Refer to Chapter 4,

BIOS

, for more information.

Can I upgrade my VXIpc 800?

You can upgrade the modular CPU card to upgrade the processor. Contact National Instruments for information.

How can I boot from an external SCSI hard drive? In the Setup/Standard window change the Master drive setting from

User to SCSI, and make sure that SCSI is enabled in the Setup/Chipset

window.

Can I use the internal IDE drive and an external SCSI hard drive at the same time?

Yes, but you can only boot from the internal IDE drive in this configuration.

My CMOS is corrupted. How do I set it back to default?

1. Select Default/Optimal.

2. Save and exit.
