I have got this problem too, only different.
I use 4977 and ftp with evox 3752.
When I access D drive with flash fxp or cuteftp, I dont see the C drive, but get the contents of my evox boot cd.
I can see the default.xbe and dummy file, so is definately not the C drive and the cd is sitting on top of my TV, so have no idea where it is getting this info from!
I have tried switching back to evox D6ef bios, but that didnt help. Have also tried cold booting everything, but is still there.
Boxplorer and xcommander see the drive fine, so I think it must be a bug in evox dash or a setting in flashfxp.
Anyone had this or fixed this?
