AlphaPC 164UX Jumper Configuration
3–3
Bcache Size Jumpers (Option 14,15)
3.2 Bcache Size Jumpers (Option 14,15)
The Bcache size jumpers are located at J28–27/28 (Option14) and J28–29/30
(Option15), as shown in Figure 3–1. The AlphaPC 164UX-2/-4 is configured with
2MB/4MB of Bcache during production ; the other jumpers shown in Figure 3–1
(0,1) are for other implementations.
Note:
The standard motherboard is manufactured with 128K
X
18 or 256K
X
18 data SSRAMs.
3.3 Boot Option Jumper (Option 11)
The boot option jumper is located at J28-21/22 (Option 11). The default position for
this jumper is out (Figure 3–1). This jumper selects the image to be loaded into mem-
ory from the system flash ROM. With the jumper out the ARCSBIOS firmware is
loaded. With the jumper in, the Safe ARCSBIOS is loaded.
