2.3 Configuration Settings
The UP1500 has one configuration switchpack, SW1, which has selectable
settings. These switch settings are organized as follows:
!
Switches 1 and 2—Firmware image selection
!
Switches 4, 5 and 6—System bus speed selection
!
Switches 7 and 8—L2 cache size selection
The location of SW1 is shown in Figure 2-1, in the upper-center of the board.
2.3.1 Firmware Image Selection
Configuration of alternat e fi rmwar e is manage d thr ough setting of switches 1 and
2 on SW1, as shown in Table 2-3. Switches 1 and 2 are On by default, which
boots the UP1500 under SRM Console.

2.4 Initialization Strapping
The UP1500 has another two switchpacks - SW2, SW3 - which describe the
strapping of the AMD-761 System Controller.
2.4.1 System Clock Speed
System clock speed is encoded using Switches 1 and 2 of SW2.
2.4.2 Disable Divider
Special clock test mode that accomodates a large skew between the 1X and 2X
clocks is enabled using Switch 3 of SW2.
2.4.3 Inclk Delay Enable
Inclock delay of the AMD-761 System Controller is enabled using Switch 4 of
SW2.
2.4.4 CPU Clk Hist
Amount of hysteresis applied to the SysDataOutClk[3:0] and SysAddOutClk
inputs for noise immunity is encoded using Switches 5 and 6 of SW2.
2.4.5 AGP Clk MUX
Input to APLL clock mux for PLL test mode is sel ected using Swit ches 7 and 8 of
SW2 and Switch 1 of SW3.
