I'm not talking about running GEOS from a SD2IEC, but using a SD2IEC (not as D64/71/81 disk image, but as the real device: browsing its tree structure, mounting / unmounting disk images found there, launching programs, etc.) under GEOS. Is there any setup / programs which can do it? The only one I'm aware of (after googling around a bit) is this one, anyone has ever tried it out?

If geos has a device driver made for it, It should work

The closest thing I've seen was a youtube video of Wheels128 in which you could distinguish an A: device with the icon of a CMD-HD named "sdiec".

I don't know of such software, but the SD2IEC supports most of the CMD-HD commands. Using CMD-HD drivers, you should be able to change partitions and view directory structure / files... but I think this would only work if you have native CMD partitions on your memory card. These are .DNP (or .DMP, files... I forget!), but last I checked, SD2IEC doesn't support CMD image formats (D1M, D2M, D4M, DNP).
Browsing the real (i.e., FAT) directory structure would really need some special software, because GEOS normally uses track & sector references which don't apply to FAT. GEOS has to use them to implement VLIR files (also the info sector/icon of each file).
Speaking hypothetically, GEOS could work with SD2IEC if the memory card used NTFS format, because file streams could be used to implement VLIR records and the info sector. But of course most memory cards have FAT not NTFS and more important, SD2IEC does not support NTFS.
In short, native GEOS and even with CMD-HD drivers, the system is limited to just under 16MB due to the reliance on track & sector references. Unless you have a memory card less than 16MB (rare these days) there is no possible way it could work normally. I undersand you don't really want/need normal operations so it should be possible with some custom software. But I don't know of any.
Now I'm repeating myself, so I'll shut up.
OK, one last thing: looking at the read me for that GOES/UIEC software, it seems it does not support real browsing of SD2IEC either! You must create a special named directory(s) in the root. One directory for each disk image type. Then you put all your D64 images (for example) in the GEOSD64 directory. When you run the program in GOES, it lets you switch to a different D64 image in that directory. This assumes GEOS/CONFIGURE has your SD2IEC device as 1541. If you have it set as 1571 or 1581 then you would need a directory called GEOSD71 or GEOSD81. It says it supports DNP images as well (under GEOSDNP), but that only works under Wheels.
So I guess SD2IEC supports DNP? Still I don't think it supports D1M / D2M / D4M images.

Werner Weicht released UIEC-Manager for GEOS some 2.5 years ago Thanks Tokra! Yes, that's the same software I was referring to in my first post.

Yes, SD2IEC seems to support DNP, but in order to use it with GEOS (ie boot from a .DNP disk image, apparently works for Wheels only) you should first load into your SD2IEC a (fake) CMD-HD ROM via this command: @"XR:FAKEHD.BIN" This is needed because GEOS (Wheels) performs a more through scan of device rom (via M-R operations) to detect a drive type, and the standard mechanism supported by the SD2IEC firmware is not sufficient in case of CMD_HD emulation. Fake CMD-HD and CMD-FD roms can be downloaded from SD2IEC firmware site.

So I downloaded the UIEC manager as indicated in the first post and started to play with it.
First off it does not work in 40c mode only in 80c mode. It does not appear to be a true file manager. It is some sort of autoexec application that allows you to switch GEOS images after booting. Apparently, to be useful, all GEOS files (images) need to be placed in a special folder of the SD2IEC.
After the initial attempt I stopped as I am trying to print and read the instructions.
Given that the SD2IEc is a storage device, I was wondering what would happen if I extract the GEOS files and place them in the root of the SD card. Would I be able to boot GEOS?
I got that idea when reading a comment in another forum about the usage of the SD2IEC.

Though I've never run GEOS from the SD2IEC, yes, from what I've read, you have to put all files in the root directory.

I was able to set up a working D81 with GEOS128, the RAMLink, the UIEC driver, and the FMradio booting from the SD2IEC.
Next I'll try the trick above and extract the GEOS128 files directly to the SD card. A different one.
