When my Duo 230 boots up, I've noticed this reported in the About screen:
24-bit addressing => System 7.5.5 uses about 18~19 MB of RAM.
32-bit addressing =>System 7.5.5 uses about 2.5~2.6 MB of RAM.
This machine has 24 MB of memory between onboard and expansion module. So this makes a pretty significant difference. Given the dead PRAM battery, enough that I'll usually change the setting and reboot if I'm using it for a length of time. Beyond that I don't seem to have any issues running in either mode and looks like the Duo 230s had a 32-bit clean ROM. Doesn't seem like anything is missing, although it seems odd that 24-bit mode can claim that much RAM is being used by the system.
I'm curious, does anyone know if there's anywhere that explains this phenomenon in some detail?
