Is It Possible To Use 256mb Smc's?

[jamessmart]

is it possible to use 256mb smc's and if it is how would i go about doing it???

 

[declaration]

no

 

[claus]

No only 128 mb or less

 

[Vimacs]

i dont think you can buy smc's with more than 128mb

 

[jamessmart]

but i thoought you could get a voltage adapter or something??? gp32_console

yeah but it must be a 3.3v smc and it's very difficult to find a SMC 256 3.3v.
and the bios has no limit to read only 128Mo.. it was a legend.

if you would put a 256MB 3.3v SMC in your GP32, would it work or not ?

 

[falken80]

I think it works yeah. But to error is human

If you find a smc 256 3.3v and no more.. try it and say us if ot works

sigh... how many more times? A 256mb SMC is GUARANTEED *NOT* TO WORK without recompiling everything that used it, eg. the bios, and every program that accesses the card. Yes, that includes 3.3v cards.

The only chance it'll work is if it pretends to be two completely seperate 128mb cards, and by then you may as well have two 128mb cards anyway.

 

[falken80]

cool Squidge.. but a french guy say me it works.
OK it's maybe (surely) a liar...

so don't try it.. Squidge know more about that than me.

 

[Vimacs]

well couse of the block sturkture it could *work* but you could only use the first 128mb

 

[falken80]

ok now it's clear for me

 

[EvilDragon]

Yep, Mr. Spiv once said that only the first 128MB are adressable by the bios (AFAIR).

And if it's something with bios - Mr. Spiv is the one to believe

Well, if the topic is closed, how come I can still reply?

Anyway, 256MB SMC does not exist. I tell you what, here's a challenge: if you can find and actually buy a 256MB SMC card (of whatever voltage), then I will buy it off you for what you paid plus US$50.

There have been stores that advertised 256MB SMC, but it always turned out to be a mistake. I think that they are the reason for this lingering question about whether they are available.

As for software support, well the first thing the software does is it looks at the SMC's ID to find out what size it is. Samsung has never defined an ID for 256MB, and so no software supports it, and so if you did plug one of these mythical 256MB SMC's into your GP32 the software would bork on the ID and the card would not work at all.

Would It be possible to partition flash memory? Partition a 512mb card into four patitions of 128mb and have a boot loader in the bios or firmware to select the partiton?

 

[RockOut]

But, if you got an XD adaptor, and a XD card, the bios should be as easy to modify as a bios on a computer, right? :huh:

 

[EvilDragon]

I don't think so - as no Converter supports more than 128MB (as already said, that's the maximum that exists out there.)

only if this is done in hardware before it gets to the smc slot. can't be done in the bios.

i think ive seen some with "up to 512mb" printet on.... maybe some hw guru have to test what he can get out of it. but xd cost realy much :-(
