Don't bother buying these SBCs made by Micro Industries in particular. Main issue: their firmware is *proprietary*. Even they are standard PC chipsets and processors.
I have two. Pentium based 266mmx BGA 2.0V using TX chipset with phoenix pico bios that is fixed and will only boot directly to vxworks (says "starting Vxworks"), and other one is mini ISA card using C&T chipset and regular 5V 486DX2 with 256K cache module that doesn't boot at all, and came with 1MB 72pin simm, brain dead idea for that especially 486DX2 66.
Worse still, the owner of this business closed up shop and cut all support off completely when owner retired when couldn't find successor to run his business in 2015. What I can best as I can, couldn't find the links that goes to manuals and firmware even their website is very limited, basically just specs of products and please "call" us for anything else, very Apple-like.
Only way is to find alternative firmware from other makers and these SBC is expensive and the sellers who have them is not aware of these issues, and I'm sure lot of users who used them previously, already converted to alternative SBCs due to restrictive designs.
Other than that, they were high quality but useless.
