Once I copied over and installed the ACECARD3 driver mine would recognize the larger cards I had, however without a working CF card first I couldn't get it onto the 100LX, so it was a catch22, but the 32mb card bridged that gap, allowed me to copy over the driver and get larger cards recognized.The 200LX will read up to a 4 GB Sandisk SDCFB/SDCFJ card,
with the appropriate driver.
Mine does, anyway. I'm pretty sure the 100LX will too.
That said, this is still an 80186, 640k, CGA, MS-DOS rig, its not like I need THAT large of a card in it, 32mb might be a bit on the small side, but I think a 1gb card is way too much, lol
Also, I have heard that the 200/700LX has broader CF card compatibility than the 100LX does, but I believe the ACECARD3 driver levels that play field fairly well.
