The debugger & memory dump does not allow to show any data above 2GBytes using Large Address Model.

Steps to Reproduce:

  // Using  pc with >= 4Gbytes on XP / 3G or Windows 64bit
  // XP example: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP 3GB" /NOEXECUTE=OPTIN /FASTDETECT /3GB /userva=2800

  // 1. set breakpoint below on FreeMem
  // 2. click on Watch List
  // 3. add LP on Watches List using Ctrl-A
  // 4. then you have to see an address starting with $A.... to $F....
  // 5. hit ctrl-Alt-E to open the Memory Dumper
  // 6. on memory 1 hit Ctrl-G
  // 7. Enter Addres of LP using $yyyy'xxxx
  // 8. you will get: Unable to get address of '$....'

use the attached example and set the break point on freemem and then use steps above (using the Windows with at least 4 GBytes of System RAM.

Some workaround given from Chris Hesik:

"Integer($FFEA0010)"

Even works:

"Integer($FFEA0010+$20)" or
"Integer($FFEA0010)+$20"
