According to the Philips web site this device became obsolete in Dec 2004. It is a flash part that only offers parallel programming i.e.no serial based ISP or ICP. As far as I am aware, Flash Magic only supports ISP devices so the device you mention is not supoorted by it. Sounds like you need a regular parallel programmer.

P.S. I have been working on some Linux tools for programming 8051 parts but so far these only cover some ISP devices. See my page at http://www.8052.com/users/redtommo
