what about initrd.bin?
where should i find it?
(Note: by the time I finished to type this post, the thread had already moved on, and it is probably not very relevant / needed anymore, but I'll post this nonetheless as it may be usefull to other users later...)
Let's try to see if I'm better at understanding online translation engines! (no warranty, though... there are big disclaimers everywhere when you try playing with that kernel update stuff, and I didn't spend time to translate them, but I suppose that you already know that bad things can potentially happen to your Zaurus! )
Warning: it seems that I didn't get it right, Ragnorok used these translated instructions to reflash his C1000, and couldn't switch it on again after a seemingly successful reflash, so there is obviously a problem here. I'd advise against using this post to reflash your Zaurus until the cause of the problem has been found. This post will then be re-edited and I'll remove this warning...Here's what I understand from Tetsu's instructions (automated translation edited for clarity and to remove stuff that doesn't apply to the C1000. Warning, the links (kernel image and modules) are valid only with the v18a version, the latest at the time I write this):
Kernel update procedure:(1) Download updater.sh.c1000 from
Sharp's developer website.
This page contains a big disclaimer, and a tiny line with the link to the file. Here is the direct link to updater.sh.c1000. Once you have this file, rename it to updater.sh and copy it at the root of an empty CF or SD card.(2) Download the c1000 kernel image from
Tetsu's website and rename it to
zImage, then copy it as well on the CF or SD card.
(no .bin extension, and mind the case, as usual!)(3) Check that there is no other file on your memory card except updater.sh and zImage. (in particular, you must
NOT have a initrd.bin file on your card!)
(4) Follow Sharp's website instructions for kernel updating. (see below)
(5) Install the
C1000/3000 Special Kernel's associated modules (.ipk file) after the next boot.
And here are the instructions on Sharp's website (that's the page where you get the updater.sh.c1000 file):
Sharp's Linux kernel update procedureThis is the procedures to update the SL-C1000 Linux kernel to the latest one. Please follow every step one by one in the following order.
1) Prepare your SD or CF memory card (which must have at least 16MB empty space or more) in order to update the Linux kernel.
Do not format with FAT16 (or FAT), or do not reformat the memory card after purchasing it. The first partition on the memory card must be a vfat partition.
Make sure that the SL-C1000 can recognize the card by inserting it in the Zaurus and checking that the SD or CF card icon appears in the taskbar before updating the Linux kernel.
2) Copy the updater.sh and zImage files on the memory card's root directory, and make sure that there is no other file in that directory. The zImage file must be at most 1260KB, and the updater.sh (for the C1000) file size is 2560 bytes.
3) Back up your personal data to PC before updating the Linux kernel.
4) Turn off your SL-C1000.
5) Insert the memory card in the SL-C1000. Do not insert any other card during the kernel update.
6) Make sure that the AC adapter is connected to the SL-C1000 and operating (charge LED must be illuminated). Make sure that the battery is charged enough before updating the kernel. You won't be able to proceed with the update if the orange battery LED doesn't illuminate.
7) Set the battery compartment switch to "release" and remove the battery cover. Wait for 30 seconds, then push the reset switch (inside the battery compartement) with a pen tip, then reinstall the battery cover and set the switch to "lock" again.

Check that the orange battery LED is illuminated, then press the "Power" button while keeping the "OK" key pressed until you see the maintenance menu (in Japanese).
9) In the maintenance menu, select the fourth entry (
4.アップデート).
10) Depending on the type of card you copied the files to, select either the first (
1.CF) or second (
2.SD) menu on the next screen, then select "
はい(Y)" to confirm your choice and proceed to the update.
11) The Zaurus will display "
Successfully Completed. Please reset" after the kernel update, so at that point perform again the step #7, then switch on your Zaurus normally.
Do not interrupt the update process and do not remove the AC adapter during the update, unless you turn your Zaurus into an expensive paperweight!
I hope that I didn't make any big mistake when editing the text, and that the few users on the board that do read Japanese will help me correct these instructions if there's anything wrong... One word about the memory card format: it seems that Sharp recommends using a vfat partition (or the online translation engine got it wrong), but I've had some success with a FAT16 partition nonetheless... Go figure! Any input on this subject is welcome!
