Sdhc In Debian, It works! Options

[ZDevil]

Today I bought an Eee PC 4GB (just ~375 usd) for my sister, together with a Toshiba SDHC 8GB (just another ~55 usd). I inserted the SDHC in the SD slot of my 3200, dmesg shows this:

CODE

mmc0: card 8001 removed
mmc0: unrecognised SCR structure version 1
mmc0: new SDHC card at address 7302
mmcblk0: mmc0:7302 SD08G 7864320KiB
mmcblk0: p1

The card does mount and I can read and write on it!
Now i am really tempted to buy a new one for myself.

whow i'm impressed ! i thought we could never add brand new device to our zaurus
now perhaps SDIO card would work too no? ....

......

what ? you bought an eee ?????????

[ZDevil]

Oh, the Eee PC is for my sister. I will keep it first for a couple of days to do some fine-tuning (and to satisfy my hunger for geekiness...). There is a lazyeeepc package which unlocks some very cool hidden functions, such as being able to apt-get install debian packages directly.

[ZDevil]

So, 2or0, is this the magic of the yonggun kernel?

This sounds like a cool little item, but I have a few questions.

1- Could the 4GB HD be replaced with a higher capacity CF card?

2- How is the touch and feel of the keyboard ... I know my Kohjinsha keyboard really sucks. I have to literally "poke" the keys to get them to register. Also the pics on newegg.com seem to suggest the Eee has an English (United States) keyboard... would this be correct?

3- Does the SD card sit flush when installed like it does in the Zaurus, or does it stick out like the Kohjinsha? Also will it take the conventional SD cards, because I have a lot of them.

Thanks,
Doug

Great! My Toshiba SDHC class 4 4G card works also! Copy files in & out is positive, but cant do much tests as its belong to my DLSR. Wonder if hardware design confines the interface speed. ZDevil, can u do benchmark tests (Come on, yours's new haha ) ?

As for SDIO, I tried a Eagletec SD Wifi card but dmesg shows nothing. Well, the positive side is that my Z still responds with the card, while in Sharp, pdaxrom etc the Z simply freeze up.

EDIT

... How is the touch and feel of the keyboard ... I know my Kohjinsha keyboard really sucks. I have to literally "poke" the keys to get them to register.

Your kohjinsha should be the SA series? My SH6 keyboard is great. Actually, I'm replying with it right now!

Right, the SA1F00A.

1. Probably not. The SSD and the CF card have different form factors, afaik.
2. The keyboard feels great. It's just like any other USB extenal keyboard. I can type pretty fast despite my big figures. But you may have a hard time if you have long nails. I got mine here is Hong Kong, and the keyboard layout is the ordinary US type.
3. The SD card is fully inside the card slot. And yes, any MC, SD and (many) SDHC will do,

Here you go...

The followings are the simple benchmarking using hdparm -tT three times for each card, done on my C3200 (debian sid).

Now I'm getting hungry for one.
Newegg.com has the 4GB Surf for 349.99.

EDIT...
From looking at the photos here at newegg, there appears to be a single button the full width of the touch-pad, instead of right/left buttons.
Could you comment on that please?

Thanks for the info,
Doug

True. There is only one long button below the touch pad. It functions as the right click mouse button.
To scroll you can swipe your finger along the right side on the touch pad, which needs some getting used to. The touch pad is very sensitive and easy to use.
I strongly recommend installing the lazyeeepc package, which unlocks some very cool features, including apt-get (all debian i386 packages!), RMVB decoder and skype 2.0 video version.
With the full desktop mode you have a full KDE desktop environment that does the same things as in other distros.
So I don't see any urgent need to install other distros.

[dougeeebear]

Thanks ZDevil for all the helpful information.

I think I'm going to get me an Eee, probably the el-cheapo model without the webcam because I have no need for it and it'll save me 50 bucks.
Or I could spend the extra 50 bucks and get a webcan I don't want plus a higher capacity battery that will give me another half-hour of battery life.
Hmm... the extra battery life isn't worth an extra 50 bucks, but an extra battery would be worth it.

I particularly like the fact that a Linux distro comes pre-loaded and configured, although I'm not familiar with Xandros.
But if it has a full KDE desktop environment it's got to be good.

Doug

True. There is only one long button below the touch pad. It functions as the right click mouse button.

I've read a few reviews that state the mouse button is sort of a rocker style button.
Press the right end for right-click ... press the left end for left-click.

Also, I would expect a tap on the touchpad is a left-click like any other touchpad, but I haven't read that anywhere yet.

That is correct, the bar is a rocker and it performs both the left and right mouse click. I love my E, but unfortunately haven't touched my zaurus since.

I've been booting my C1000 with Debian EABI off of a Lexar 4GB SDHC card for about a week now...the latest Angstrom kernels recognize it without problems.
