One more tip for the software update.
Please try the update with a SD card (not a SDHC).
I remember people complaining about problems with software update when using bigger cards (4GB, etc.) although these cards work well for normal game loading.
BTW: Your SIO2SD has a firmware version 1.3. I could see it on the attached photo.
You win the Interwebs today sir. That did the trick. Inserted a 2GB SD card and bam, the firmware updated. So SD for firmware updates and SDHC for everything else. Learned something today. Cool!
If you had 3.1, it would tell you what version you had when you first powered it on.
If you had 2.5, it would tell you that version when you entered config mode by holding SHIFT at power on.
I was able to upgrade from 2.5 to 3.1 by putting sio2sd.bin in the root directory of the SD card, entering config mode with SHIFT, and then pressing SHIFT-K3. This took a while because I got K3 and K2 confused.
The upgrade was successful, except that I can no longer select disk images from the Atari 800XL. I installed a default boot image, which kinda works, but when I select a new disk image to boot from, my selection is ignored and it just boots whatever it was going to before.
So after getting that advice from TheMontezuma and updating the firmware you are correct 3.1 does show the firmware at the cfg tool screen. I have no idea what version I had previously because the SHIFT at power on did not show it, but all is good now.
I have two Lothareks and neither shipped with the latest... they both had 2.5. Technically 2.5 is the latest non-beta though...
You probably want 3.1 rc2 though...
You are completely on the money. After taking that advice from TheMontezuma on using a SD card and not a SDHC card for firmware updates it updated me to rc2. So you are right in saying it is not shipping with the latest. I wonder what Lotharek was saying then that he ships all drives with the latest? Odd.
Either way, thanks guys for all your help in navigating this. You all have been very informative.
