- Yes - your memory is being mounted within the 24-bit DMA address range
- (i.e. the 8MB Zorro-2 autoconfig memory area).

- I suggest you read the manual that came with your card. The Combo allows
- you to change the location of the 32-bit RAM to be above the 24-bit DMA
- range. Depending on the jumper settings either some or all (the best option
- in your case) of the 32-bit RAM can be moved. This would allow you to get
- the 4 MB of 16-bit RAM on your dataflyer back. GVP termed this concept
- "Extended RAM".
