AdapterId 080C5H ARTIST 1000 MC Series  Version 1.1

PC I/O Address
     <03EXh & 07EXh>, 02CXh & 06CXh, 02DXh & 06DXh, 02EXh & 06EXh 

PC Memory Address - Below 1MB
   The default PC memory address is 0xCC00. This 16 KB block in PC memory maps into two 8 KB windows in the GPX memory space.  These 8 KB windows can each be mapped to start at any 8 KB boundary in the GPX memory space.  By using the system configuration utility to configure memory usage the user is assured of a non-conflicting selection. If the PC memory address is configured as disabled the software you are using with the ARTIST 1000 MC Series graphic controller will use the default. 
     <CC00-CFFF>, C800-CBFF, D000-D3FF, D400-D7FF, D800-DBFF, DC00-DFFF, Disabled 

Data Bus Sizing
   The 1000 MC Series can operate in a 16 bit or a 32 bit Micro Channel card slot. 
     <32 Bits>, 16 Bits 

Interrupt Level
     The 1000 MC Series can use Interrupt 5, 7, 10, 11 or interrupts may be disabled 
     <Disabled>, IRQ 5, IRQ 7, IRQ 10, IRQ 11 

PC Memory Address - Above 1MB
     A PC memory address above 1MB should only be used for UNIX systems. The default is that decoding above 1MB is disabled 
     <Disabled>, 2MB - 4MB, 4 - 6, 6 - 8, 8 - 10, 10 - 12, 12 - 14, 14 - 16
