I bought my DC console, on, or around the beginning of December of last year, superficially for trying out either Linux, or say another related OS, on it. So far, I have tracked down the usual collection of resources, including several pages on a site that I find mentioned on the ECOS pages, at Sources Red Hat. Have you had any luck getting your DC to startup using Linux? And can you send me a CD, to try out, if I were to supply my hard mail address? E-mail me off list with your details. I regret that I can not actually support your flash problems. ------------------- Gregg C Levine hansolofalcon@worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."
