Installing a Texturing Accelerator
This section describes installing an optional texturing accelerator on a Z10 board. Adding a
texturing accelerator creates a Z10-T graphics accelerator with 8 MB of texture memory.
NOTE You must remove the Z10 board from the system to install a texturing accelerator.
To install a texturing accelerator to a Z10 board:
1. Shut down the system and turn off system power.
2. Disconnect the cables from the Video and VGA ports on the back of the system base unit.
3. Open the system base unit as required to gain access to the PCI option board slots. Slots
are identified in “Connecting the Video Cables” later in this chapter.
4. Use a quarter-inch nutdriver to remove the screws that secure the Z10 board to the system
chassis. Retain the screws.
5. Remove the Z10 board from the system.
NOTE The new Z10-T board set requires two adjacent PCI slots.
6. Use a quarter-inch nutdriver to remove the blanking plates from the following PCI slots:
Z10 board, desktop system: PCI slot 3
Z10 board, deskside system: PCI slot 4
Retain the screws.
7. Remove the texturing accelerator from the antistatic bag.
8. Using a Philips screwdriver, remove the two screws from the Texturing Accelerator I/O
panel shown in the following figure.
9. Align the texturing accelerator with the Z10 board. Insert the two captive screws of the
texturing accelerator with the standoffs on the Z10 board and tighten the screws. Refer to
the following figure.
CAUTION When tightening the captive screws, alternate between the screws using two turns each.
