This would be a great feature for any OS. I'm not sure how fast the memory would be on one of these flash drives compared to regular ram though.

Would be awesome for the Efika if you ran into a situation were you needed more ram on the fly.

How would that differ from any other VM approach?
If MOS had VM support I am pretty sure, it wouldn't make any restrictions regarding the used vorlumes (logical) or drives (physical).
The bottleneck still keeps being the relatively slow ide bus (+ca. 10 MB/s) or usb1.1 (with 1.5 MB/s totally out of dicussion).

Neko's idea to utilize gfc card mem sound even more interesting than the above, while I still think the best approach with the efika is just to not overstep the 128MB limit (though VM would be nice as 'security backup' to not render the sytsem dead when out of ram).

VISTA doesn't use USB sticks as system memory. This is not the point. Readyboost will monitor prefetched data that is to be sent to virtual memory and instead direct it to a more responsive memory device--a USB drive, SD Card, Compact Flash, or other flash memory device that is connected to your computer.

Readyboost works only with high speed usb sticks, fast responsive ones. I tried several usb keys for it and none of them was fast enough to enable the feature.

It's nothing but a replacement for virtual memory /swap
Don't expect to have anything smilar on Efika.

> It occurred to me that this would be a valuable feature for MorphOS for Efika.

Don't believe this kind of Microsoft marketing bullshit. Using a swapping pagefile on a harddisk is bad enough, but on flashrom, this is going to be either slow (except for the seeking time, flash has no advantage to a harddisk) and/or a waste of money because FlashRoms only have a limited amount of rewrite-cycles (usually in the six digits range) and when using the flashdisk for "virtual memory" the thing is probably dead within a month.

That's under optimal conditions on far better bus/cpu combo than the efika can ever hope to achieve. In real world use on the efika you can expect far, far worse performance...

I seriously don't understand why you keep clinging to this, the efika in its present form is not usable as an end-user product (it's far too impractical to assemble and has no reasonable way to expand it with memory or f.ex. a dvd drive), if anything it can't be considered as anything else than an evaluation prototype for some embedded product (where you can call the shots on the specs for the final product depending on your needs). If you enter into it thinking anything else you'll be gravely disappointed.

Who said it's unused? By mapping away graphics memory for other use you are permanently impairing the capabilities of your graphics card for other tasks (which will even further compound the slowdown of your system).

CISC: What's so hard about connecting a DVD drive? The IDE connector only takes one unit, or what?

Ok, you need some kind of case which won't be easy to find, but connecting it doesn't seem like so much trouble to me.

that's all i got !

Apart from the rumour (by Neko) that a slave unit won't work properly on the efika you'll find that it's quite tricky to connect a slave dvd drive to a 2.5" connector .. esp. a slim-drive as they have a quite special connector that needs an adapter, and these adapters only come in 3.5" variants afaicf...

Well, I've seen Amigas 1200 working with a meter of cable coming out of its internal, unbuffered IDE interface...

I guess bplan is collecting here a widh list for the next batch of Efikas, right? I wonder why anyone hasn't asked for this yet:

Could you guys take out the joke of the ATX connector, and add a 12 VDC input, for an external power brick? I think there is space left on the board for the required regulators. They should be small and cheap, because the Efika has such a low current draw.
