BIOS and BARs

[ABIVEN Anne <ABIVEN@crf.canon.fr>]

I am now testing a PCI board under DOS. Only two base address registers are 
set. BAR 0 requires 4kbytes of I/O space and BAR1 requires 4kbytes of 
memory, under 1Mbyte to be seen by dos.
At boot, the PC (the BIOS) does not give any warning message or error 
massage but when I look at the content of my BAR1 I see that it did not 
implement it below 1 Mbyte but on top of the 4Gbytes, so I cannot access my 
board under DOS.
Is it normal that the BIOS gives no warning message when it does not respect 
the requirements given ?
Is it normal that a PC with nothing else than this board (with 2 BARs only) 
is not able to satisfy these requirements (4kbytes of memory)?

Thanks

Anne
