Minix support is ridiculous, might as well sell faulty unit for 5£ and buy new one.
I once had a problem with mine, and after a few days (yes days) of e-mail changing they asked me to send unit to re-seller, and re-seller was gonna send it back al the way to HK.
It would take 30-40 days to get there, another sum of days to get repaired, and back to me again. phew.
That is a no no for me, and should be for most of you. obiously i bought a new one, cause i didn't want the hassle of waiting those longs days.
On the other hand, with my other box (Wetek) i had to replace the unit, and the company sent a TNT pick up to my house, and 3 days later i got a new one, again brought by TNT to my house. Now that's what i call premium.
