3.3 JUMPER SETTING
Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks. (A jumper block is a small
We will show the locations of the
CAUTION: Do not touch any electronic component unless you are safely grounded. Wear a grounded wrist strap or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can permanently damage electronic components.
3.3.1 Memory Type Setting (M1 ~ M4 & JP1)
Before installing the memory into memory sockets MEM1 through MEM8 you have to configure the memory type which will be used (ROM/RAM) on the
You can configure the
It is not necessary to insert memory chips into all of the sockets. The number of SRAM chips required depends on your RAM disk capacity. The number of EPROM chips required depends on the total size of files that you plan to copy onto the ROM disk and whether or not it will be bootable.
Insert the first memory chip into MEM1 if you are going to configure it as a ROM or SRAM disk. If you use a combination of ROM and RAM, then insert the (FLASH) EPROM chip starting with the MEM1, and insert the SRAM chips starting from the first socket which is configured as SRAM.
•M1: is used to configure the memory type of MEM1 to MEM2
•M2: is used to configure the memory type of MEM3 to MEM4
•M3: is used to configure the memory type of MEM5 to MEM6
•M4: is used to configure the memory type of MEM7 to MEM8
CAUTION: When the power is turned off, please note the following precautions.
1.If your data has been stored in the SRAM disk, do not change the jumper position or data will be lost.
2.Make sure jumpers are set properly. If you mistakenly set the jumpers for SRAM and you have EPROM or FLASH installed, the EPROM or FLASH will drain the battery’ s power.
