3. VMEtaxi Hardware Configuration for Si Readout

For Mark-2 boards running in the Silicon Readout, the following sequence of operations must be adhered to:

1. Ensure that SiVMEXI is fixed EPROM firmware at $4001'0000.

2. Reset the VMEtaxi.
   Note that if a board is already running a version of SiVMEXI it will be necessary to abort theVMEtaxi for which the level 7 vector should first be modified using the LA standalone command (see section 5). A normal abort can then be made in the usual manner by hitting the reset button momentarily.

3. Memory modify (xiMon command: M) the 9 bytes at address $1030'2F00 as follows:

   10302F00 : 00
   10302F01 : 01
   10302F02 : 00
   10302F03 : 00
   10302F04 : 00
   10302F05 : 00
   10302F06 : 00
   10302F07 : 01
   10302F08 : 00
   

4. Memory modify the ram configuration area at $1000'1FF4 as follows:

   10001FF4 : 6E (note this should be $EE if RWD is required)
   10001FF5 : 0x (x=8=No VMEbus access to XRAM, see VMEXI_SSP §3.3)
   10001FF6 : 88
   10001FF7 : 00
   10001FF8 : 40
   10001FF9 : 01
   10001FFA : 00
   10001FFB : ii ($28 = Si-master, $38 = Si-slave, $3C = Si-STC)
   10001FFC : nn (where nn=$00 to $FF, the taxi number*)
   10001FFD : 10
   10001FFE : 30
   10001FFF : 2F
   then for the Si ring-master only !
   10001FF6 : 8A

5. Terminal i/o is disabled as default.

6. Save on EEPROM via:
