1-17Dip Switch 28 1Bit Explanation1 Address control for extended I/OOn : Software can enable/disable access to extended I/O ports. (Factory setting)Off : Extended I/O is always enabled.When this bit is set to On, software can enable/disable access to extended I/O ports (320H-32DH) by output data to32FH.Setting this bit to Off always enables access to extended I/O. Software can't disable access to extended I/O through32FH.System initializes hardware to disabling extended I/O if this bit is set to On. But BIOS setup finally determines initialstate of accessibility, enable or disable.2 Reserved for futureOff : (Factory setting)Extended I/O 32DH bit5 reflects to this setting. This bit is reserved for future enhancements and any functions are notcurrently assigned to this bit.4-3 Signal to open drawerbit4/3 is Off/Off : 217msbit4/3 is Off/On : 145ms (Factory setting)bit4/3 is On/Off : 108msbit4/3 is On/On : 72msThese bits define the period to activate signal for drawer open. Do not change these bits unless electrical specificationof the drawer is modified in future.5 Type of customer displayOn : Dual line typeOff : One line typeThis bit is used to get type of customer display, one line type or dual. This bit actually reflects the status of dip switch2 bit5. Setting this switch to OFF returns 1 to this bit.Extended port 32DH bit0 reflects to this bit. This bit should be set to indicate the customer display type actuallyconnected if application program has a capability to adjust data for each display type.6 Reserved for futureOff : (Factory setting)Extended I/O 32DH bit1 reflects to this setting. This bit is reserved for future enhancements and any functions are notcurrently assigned to this bit.8-7 Type of LCDbit7/6 is11 : VGA (640x480)10 : SVGA (800x600)01 : XGA (1024x768)00 : Reserved.Bit8/7 is Off/Off : VGA (640x480) (Factory setting)Bit8/7 is Off/On : SVGA (800x600)Bit8/7 is On/Off : XGA (1024x768)Bit8/7 is On/On : Reserved.Extended port 32DH bit6/7 reflects to these bits.
