I recently acquired an ACA500 last week. No matter what I try, I do not see more than 1.4MB FAST RAM under WB 1.3. I already checked through all the settings that were suggested here and on other sites. MapROM is definitely off. I do not yet have CF cards inserted so any memory taken for that is not to blame. "ROM" is set to "keep current".
My A500 is a rev 6a motherboard with the 1MB CHIP RAM hack. 512k trapdoor RAM expansion is a SupraRAM rev 2. Kickstart 1.3 is in ROM.
ACA500 is using the latest firmware. I also did a simple return to defaults but that did not help either.
In addition to not seeing all the FAST RAM, my RTC is not recognized (works fine with ACA500 removed).
Attached is my system configuration screen.
Is there anything else I need to check?
