Flash Chips

I am aware of the micron drop in replacments however i
still cant match the numbers, i will open up my x30
again and reread the numbers as the pictures i took of
the flash chips make it to hard to read the numbers.

thanks for the info however, i guess i will have to do
a bit more R&D into the numbers, it reminds me of the
after market mods you can get where they increse your
ram, i wonder if we could do this for flash. (they
have a mod to increse the ram in a X50 to 128MB)

as for the x50, i personally would go for the x50v :),
from analysing the design of the x30 i have notcied
that there is an area for the wifi modual, i belive
that they would take this ideolagy and apply it to the
x50 so that the soldering of the video card (which is
a very nice chip) would be optional, i cant confirm
this thogh.

from that info i would also belive (and i recall some
people on the aximsite.com forum talking about it)
that the LCD screen is connected to pxa270 directly
and that the frames are transfered from the Video
card, i belive this becase if you want to have a dual
head machine the pxa has exclusive acsses to the pda
LCD screen and the video card has exclusive acsess to
the monitor, therfore there is no mixing and matching
(ie the video card cant touch the pxa's frame buffer
at all only the video out port) therefore you lose any
graphic enhancment when you use video out unless you
want to copy each frame back to the pxa after
rendering (which is why betaplayer recomends turning
off the pxa screen when playing Xvid or Divx movies to
decreses the bus usage of moving frames back and
foward

the video card has a nice 16MB of dedicated ram and is
openGL ES complient (both a superset and subset of
opengl at the same time, it adds alot of 2D stuff for
mobile phones) it also somes in 2 flavors, one with
384KB SRAM (i belive that number is correct) and
another with 768KB memorey, for the second one this
would allow a resolution of 1024 by 768 with 8 bit
color on the video out (single buffered) and may allow
for a higher res and or color depth if you store the
frame buffer in video SDRAM instead of video SRAM with
reduced performance

because of this i belive the x50V would be a better
choice as it would probelly be easier to cut back the
x50v distrabution for the x50's rather than add more
to the x50 distrabution to add support for the x50v.

however i have gone compleatly off topic, basically it
should just use the pxa's frame buffer therefore you
shouldnt have much trouble getting messages on the
screen or over usb, not sure about serial as i have
not seen a serial cabel for the dells, i also belive
that irda should be fine in SIR mode but i am farily
new to all of this.

hopefully the designs of the 2 should be farily
simmilar, i do know that the x50 uses a diffrent audio
codec that is more capable but it is still on the ac97
bus, it has support for hardware equilizer but could
be from the same manufactrer

as for the restore combo, i know there is one for the
x30 and its the same as the one for the x3 but i am
unsure of what the x5 one is and if it applies to the
x50, i would say it does

please note that everything i have said here is
speculation from reading data sheets and may or may
not be correct
