Well, betwen the times when it lock up with no reason, does whatever it wants despite your commands, and reboots for no reason, the Quintum A200 should work fine.
Seriusly, I hope is a typo and you do not have a Quintum A200.
If you do, buy a big bottle of aspirin right now, and get ready.
The good news. I know how to make them work, and i will not charge you for sharing my misery of a experience with a200 ‘s.
Write to mike3799@yahoo if you really mean A200.
I hope you meant A400 or something like that.
