I have an A600 that simply won't work with Melcard Mitsubishi 4MB (MF34M1-LYCAT01). A600 works great with another 2MB card, it also works with CF card reader. I tried 4MB card on an A1200, and I was able to use it as Fast RAM. After I configured it on A1200, I tried it on A600, but it wasn't recognised as RAM (or anything).
A600 has KS 37.300 and WB 2.1. PerpCard detects the card, but it's "Unknown". Sometimes it is recognised as ~1500 bytes SRAM card, but after reboot, it doesn't show up. I also tried various advanced settings in Perpcard, but I was unable to do anything with it.
Am I missing something obvious?
