Hi!

This is a bit of a Newbie question, so apologies if I should have posted it elsewhere.

I've just bought a second-hand SL-5500 with a 64MB SD card and a 32MB CF card.

I would like to expand the system memory/storage considerably but I'm not sure what limits there are on the size of SD/CF memory I can use. I don't want to spend lots of money on cards if (a) the Z can't use them at all or (cool.gif the Z can only address a small part of them.

I contacted Sharp Service and was told that the limits are 128 and 192 for SD RAM and CF RAM respectively. I presume that these figures are in MB and only apply to memory (RAM/ROM) rather than storage (disk) devices.
However, this doesn't seem to stack-up with various comments I've read on the ZUG mailing lists and other places, which seem to indicate that people are using up to 1GB SD card and 512MB/1GB CF cards and also using up to 4GB CF microdrives. unsure.gif

Is there a FAQ somewhere which details what the limits are (if any) and what devices do/don't work with the Z?

Many thanks in advance,

John (slightly confused but fascinated with the idea of Linux of a handheld!)

You cannot physically expand the RAM in the 5500. It has 64MB of RAM and with the Sharp ROM image installed, half of that is used as normal operating RAM and the other half is used as internal storage (so the battery must be kept charge to keep this).

As for limits on standard SD/CF cards, you are only limited by the filesystem. Most cards come formatted as FAT16, which can only handle up to 2GB. But I would assume cards bigger than this come formatted as FAT32 which can handle a lot more. ext2 can also handle a lot more than 2GB. When people have reported problems with SD cards, it is usually due to poor card quality and this is not limited to the Zaurus by any means.

Note that for flashing the ROM you need a FAT16 formatted CF card.
