Axlon RAM on an Incognito 800

$

I feel like I can do just about anything Atari related on the Incognito 800 thanks to its beautiful engineering! One thing that has me stumped, though, is the Axlon emulation when in Coleen mode.

 

When in XL/XE mode, one can choose Stock Config, 320K RAMBO, 576K CompyShop or 1088K RAMBO. You can also choose stock OS's, Fastchip, etc. Very tidy.

 

However, in Coleen mode, you choose Base Memory first: 16K, 32K, 48K or 52K. Then of course, you can choose your OS such as Stock A, Stock B, A-Fastchip, B-Fastchip etc.

 

Also in Coleen, there is the option of choosing "Axlon Emulation" Enabled/Disabled but with no amount of memory option, etc.

 

So my questions are: 

 

1) Do you need to choose 48K or 52K for this to work properly? (Doesn't the Axlon extended RAM bank into the "unused" 4K at $C000 to $CFFF?)

 

2) Does turning on "Axlon Emulation" automatically assume 1meg of Axlon extended RAM? (And should I have the base RAM set to 48K or 52K to do this?)

 

For example, I can't get Top-Dos 1.5 to recognize any Axlon behavior in my Incognito 800 despite my goofing around with these settings. Top-Dos will enable Axlon mode but then flips out when I try to access it's RAMdisk at D8:.

 

Any Incognito experts have any advise for me?
