YMMV). I've got one of those "nice" ebox2300 boxes that use the original Vortex86 (AKA SiS 550). They're something like a 486-586 depending on how you look at it. I don't know how much they carried over to the newer SX/DX/MX variants but i vividly remember that the linux kernel configuration must be almost perfect to boot on these. I also recall that some kernel versions flat out don't like them, so trying is the best option until you find a suitable one. If you're interested i might be able to dig a kernel .config, but remember it's a different beast from the newer variants and it might not help at all. Regards.
