It was I who dun it.
The original discussions were lost when the old beeboard? forum shutdown. Discussion then moved to MSPP forum where the was some further updates done. The most recent were in the last year or so. Basically the ide 8 bit mode is selected for the cf. I had issues originally with it being fussy with regard to which cf would and wouldn't work.
Over the years others have used a similar technique and investigated it further. Search for 'rc2014' info on the internet and they researched the issues further. Some circuity changes helped but it is still a bit fussy with regard to cf's. Also search MSPP for a couple of threads on there about the CF interface.
I've updated my coreboard with some updates (see MSPP for details).
I've also designed a usb interface that allows you to r/w a fat32 formatted usb stick to use for xfers to/from pc/mbee, very handy to move data/files between systems.
re corrupting the cf, I believe that the issue was related to a bug in the bootrom/bios and have been fixed and/or reduced. The actual changes for the cf interface was pretty trivial, just selecting 8 bit ide and that was about it. I'll try and dig out a bit more and/or locate the references online.
Some early stuff is here https://sages.com.au/wordpress/?p=79 (sorry some of the referenced links don't work anymore).
cheers
