First of all thanks to everyone, especially StuBear, for all the help gettng me up and running with my C700. It's been great fun and I now have it looking just how I want.

I'd like to ask about the way Zaurii handle memory, from reading the FAQ http://www.zaurususergroup.com/modules.php...lding%20a%20ROM am I right in saying that if you reduce the number of unwanted applications by building a custom ROM, it will free up more memory which can be used as RAM (so it becomes a RAM upgrade)? If so it's something I'd like to try. Am I also right in saying that the only requirement on my Apple Mac is to be running the Terminal?

Thanks again.

There's no sane way you could use unused Flash as RAM.

As Mickeyl says you don't want to do this. RAM is accessed rather a lot, and flash memory has a finite (if long) life. Also flash memory is orders of magnitude slower than RAM.

That said, it might be possible to create a swap file in the unused bit of flashROM. But don't do it, not a good idea.

What do you need more memory for anyway?

OK guys thanks. I must have misunderstood that then. I was reading it that freeing up Memory with a smaller ROM meant more RAM. Obviously that's not the case with a PC but I thought maybe it was different on the Zaurus. It seems to me that you're saying you could only use the freed up space as a swap file and I've read that's a bad idea on the internal memory.

The basic reason for the memory increase, thanks for asking, is that I found that when I had the tkc ROM installed which I understand is a minimal system, I seemed to be able to open several programmes but with the Sharp ROM (which I am retaining for it's Japanese Language ability) I seem to run out of RAM memory sometimes with only two applications open.

With a 5500 or 5000D the standard Sharp ROMs use half of the RAM as a RAM-disk, and so in this case changing ROMs (to a non-Sharp ROM) will give you more RAM. This is not the case for the 5600 and C machines.

This could be where the confusion arose.

Ahaaa, thanks Lardman, makes me feel less like a clown and also as everyone says, I'd be wasting my time then to make a ROM.
