ShowCards v1.32 03/11/90
ShowCards is a utility which examines each plug in card on the expansion
bus and displays information which _may_ be of use in building a CardROM
list for use with Dave Haynie's SetCPU 1.5. Although ShowCards displays
information for each card in the format required for a CardROM list, the
address space of expansion memory boards is added to the system free memory
list and I can see no advantage in the use of CardROM entrys for these
expansion memory cards.
ShowCards is useful for identifying the cards installed on a given machine
without having to go under the hood. ShowCards examines each card on the
expansion bus (starting at the CPU slot on a A2000 and working left towards
the power LED). Presently, ShowCards identifies aproximately 2 dozen
expansion cards by manuafacturer and product name. If you send me MAIL
showing a dump from ShowCards and you identify any unknown cards by name, I
can expand the list of recognized cards. ShowCards is based on an example
in Appendix G of the Amiga Hardware Reference Manual.
It turns out that some cards and software drivers (the Supra WordSynch for
instance) automatically seek out 32-bit RAM and relocate the ROM image
there. Using the CardRom option of SetCPU actually caused a performance
decrease (measured using DiskSpeed version 3).
To run ShowCards, just type 'ShowCards<cr>' at the CLI prompt. A sample run
follows:
