11.DATA ACQUISITION CIRCUITRY I/O MAP

11.1 Base Address

The data acquisition circuitry on Prometheus occupies a block of 16 bytes in I/O memory space. The default address range for this block is 280h – 28Fh (base address 280). This address should work for most applications, but it can be changed in the BIOS if necessary. Go to the Advanced screen and select Advanced Chipset Control, then ISA I/O Chip Select Setup. Scroll down to I/O Window io_cs3, which is used for the data acquisition circuit. Do not change any setting other than the base address or the circuit will not function properly. Make sure the selected address range does not conflict with any other circuit on the CPU or any add-on module. Here are the proper settings:

Window state:

Enabled

Base Address:

(user selectable, default 280h)

Read/Write control:

Read/Write

Window data width:

8-bits

Active Level:

Active Low

Window size:

16
