I've just discovered a couple of upgrade ports in my Netbook (hey, you learn something new every day). You need to half open the screen and they're under two hatches that are usually hidden by the screen. The left one is a 32MB RAM module in some format unknown to me. The right one is more mysterious, and contains two different kind of chips, one of which has a paper label on it saying 'Version 011 11/06/01'. Is this the boot ROM? It's the same format as the RAM module. I hear rumours that it's possible to upgrade the RAM in a Netbook; are these modules at all standard or are they some weird Psion proprietary thing? -- ┌─── dg@cowlark.com ───── http://www.cowlark.com ───── │ "To be is to do" -- Nietzche │ "To do is to be" -- Sartre │ "Do be do be do" -- Sinatra |

The maximum memory a netbook can have is 64Mb. If you have both ports filled, you already have the max. The modules are basically both 32Mb RAM, the one on the right has an extra 2M (Mbit / Mbyte?) module that performs the basic bootstrap procedure. The OS is loaded into the first 16Mb of RAM and locked, so you end with 48Mb usable.

Missed Ed's reply by seconds - typical. Ed is correct and my mistake - the "personality" module is 16Mb and there is 16Mb on the motherboard - it has been a while :-/ The modules are interchangeable in that they can go in either slot and I seem to remember the EPOC OS is limited to 64Mb too. Once the bootstrap is done, that 2M PROM is removed from the memory space entirely and cannot be accessed. I did start a project a few years ago with another Psion acquaintance to look at accessing that boot PROM and decoding exactly what it did as well as decoding the OS headers and trying to compile new ones but due to a server crash we lost all the info we had collected and it was too painful to start again. -- John On 28 September 2010 10:52, John LeFebvre <jo...@le...> wrote: > The maximum memory a netbook can have is 64Mb.

Is there a 2.6 kernel for the Netbook yet? I've managed to scrounge up a standard 16-bit PCMCIA wireless card, and given that the Netbook has twice as much memory as I previously thought I should actually be able to get some use out of it. -- ┌─── dg@cowlark.com ───── http://www.cowlark.com ───── │ │ life←{ ↑1 ⍵∨.^3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵ } │ --- Conway's Game Of Life, in one line of APL |
