Honey_Commander_v4.00: RAM CRC ERROR...

Greetings, O venerable All! I would like to ask shell users "Honey_Commander_v4.00", adapted for advanced memory 'Pentagon-512K' (6&7 bits of port #7FFD) about the occurrence error such as 'RAM CRC ERROR'. This error occurs extremely rare, if such parameters are set in the 'Configuration' menu items like 'CRC Check' and 'RAM Check'. The error only occurs on page #08. Computer RAM works extremely reliably! I modified the memory driver myself. Everything is simple and there are no errors. It has been checked several times. _Only_ in this program I have problems with extended memory. I'm leaning towards some kind of mistake. in the shell itself. Who uses the subject quite often with extended memory, clarify the situation, plz! Does this happen to anyone else? Or put your driver for Pentagon-512K at 500:812/9.9. Best regards, Felix.
