No need to reflash existing Trinitys. The EEPROM on the Trinity is both readable and writeable from software. It's on there to store settings and such like for programs (e.g. network configuration). It's allocated with a simple system giving 120 x 1K chunks and a table which has a record of what is using each chunk. There's all the info on how it stores stuff as well as all the source code needed to do everything included with the Trinity (and also printed in SAM Revival 20) A simple program could be made to allocate a chunk (or chunks) for the extra boot code or the whole DOS, which the patched SAM ROM could then fetch when the SAM starts up. > In fact, I guess you'd just be able to offer the OS ROM as an upgrade > (?), so I guess I could order a Trinity right now and get myself in > order with whatever tiny number of discs I didn't long ago image while > the drive is still working. Yeap. When it's ready it would just need the modified SAM ROM to be fitted inside the SAM and then a program loaded on the SAM to dump the extra chunk of code in the Trinity's EEPROM and then it would be all set to go. > While the Atom and that ROM would clearly solve my solid-state needs, > it would be nice to throw some ethernet on in there while I'm spending > the cash. I'm itching to see stuff using the Ethernet up and running as you'll have seen from the latest magazine - I'll update information on my webby of what I've got in the works at the weekend when I've got some spare time. >From chatting with Adrian I know he's been making great progress with the TCP/IP code, running his DNS program and just seeing it pop the results up shows it's well on the way! With all the ideas that he has been kicking about for the completed stack it is going to be fantastic - and easy to use for all the programmers out there.
