-- Flash rom (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=9855)

I don�t understand nothing about flash rom !!!

Can help me ?

flash rom is what allows you to upgrade the OS. almost all if not all major operating system upgrades require flash rom. On normal palms, flash rom is what the OS is stored on. but its just stored on a normal rom chip on visors and therefore is nonupgradeable
