Title: Slow Cacko Rom
Post by: frenchja on July 27, 2004, 08:49:25 am: Hi Guys,

Just installed Cacko/Crow rom for the first time, what a painfully slow process it is unpacking the home dir! Anyway... The rom is so slow after doing

$su
#echo MOUNT_OPTIONS=\"async,noatime\">/home/root/.rom_options
#reboot

Anyone able to help before I ditch this rom? Also why don't these new roms fix the double reboot bug I seem to be plagued by.

Take Care,

Jamie

Most probably, the new driver mmcsd.o for the sd slot will help you:
You have to replace the orig driver in
(and rename mmcsd.o to the name of the orig driver)

Try to use updated Cacko 64/0 kernel. If it does not help you may be unlucky to have a slow SD card, sorry...

Thanks.

Hi,

From ploughing through the forums I believe the Toshiba and Panasonic SD cards are the only ones to bother with for speed and reliability (correct me if wrong). I bought a Toshiba 256 for Â£37, though Panasonics seem to be around Â£60! As you can tell I am having problems, though could be down to the rom. Will be able to prove this when the links within the ZUGs download list are res-established.

Hope this helps,

Jamie

Thanks for the response. I'll consider these two, though it would be good to know you'd sorted your possible Toshiba problem first

Lookings at products available form ebuyer.co.uk, I found:

The Kingston Elite Pro line of Hi-Speed SD cards support 4 bit data transfer at up to 10Mbps - 5 times faster than standard SD cards (standard SD cards support 1 bit data transfer).

Is this supported by the Zaurus & is that what makes the difference? If I can confirm that it'll make shopping easier

Incidentally, ebuyer have the 128MB Kingston Elite Pro at 42ukp. This appealed to me as I find their SDRAM very reliable.

The price & size differences make me wonder if this is a red-herring; in which case I'd imagine the 4 bit data xfer will either result in even better performance than Tosh/Pana, or if it turns out the Zaurus doesn't support it, a waste of money :/

Well looks like I have a slow SD card, even though people have rated the toshiba m256 on this forum! I have tried the mmcsd.o and the new kernel, but no luck still dog slow! So looks like I need to find another rom or just not use this brand new sd card

Does any1 have any suggestions?

Take Care,
