Responses from Lippert

Here are responses from Lippert to my questions on Cool RoadRunner II .=
=2E.

1) What is the Graphic controller chipset?

   The CRR2 uses the Intel/C&T 69000 video controller.
   See attached manual

2) If the above is not the CX5530 companion video (which I assume
   it isn't) its a fairly unique setup. Do you have any more info
   on how the graphic controller integrates with CX5530?

   To be PC/104 (ISA bus) compliant we have to use a external graphic=20
   controller if we want to use a Display. Reason is if you take the=20
   internal graphic controller for use of TFT displays (companion chip
   (CX5530A) you do not have all ISA bus signals and so you are not=20
   100% PC/104 compliant. Also with the CT6900 you have more=20
   possibilities to connect different types of displays like DSTN,=20
   Planar, monochrom etc. Also the speed is more fast, cause the=20
   CT6900 has 2MB (or 4MB) of internal SGRAM and if you use the=20
   internal Graphic controller of 5530A you have to use graphic memory
   with the shared memory funktion (memory shareing of SDRAM). This=20
   means the CPU calculates in one step the graphic (the piece that is=20
   used of the SDRAM depend of the resolution of the display) and on=20
   the second step the normal calculation of applications. An other=20
   reason is if you want to use PanelLink of TVOUT you HAVE TO use the
   CT6900. We just offer the VGA funktion made with the internal=20
   graphic controller, cause here you have all ISA bus signal (but=20
   memory shareing-->speed, maybe 25%less) and you save the money for=20
   the external graphic controller-->just at high quantities

3) The tech manual says that CX5530 contains state-of-the-art power
   management enabling "Deep Green" implementations. Where can I
   get more info on that? Since we are dealing with battery-powered
   mobile devices, ability to power down components is desireable.
   Are specs available that would make it possible for a program
   written in C or ASM control power to devices for this deep green
   mode, or is it something altogether different?

   BIOS supports APM, please see attached files. No further infos
   available!

4) Where can I find more info on this PanelLink standard, and how
   do I know which LCD panels will work with that over long cable
   runs?

   See here for more information on Panellink, how it works,=20
   application notes, etc: http://www.siimage.com/home.asp

5) Is the video mode for NTSC or PAL configurable in BIOS?

  (EMJ said) I believe that the video is currently PAL only,=20
  with an NTSC version coming soon.  Christian, is there an=20
  ETA on the NTSC version, or am I mistaken?
  (Lippert responds)
  Patches see attached

6) Are my power figures correct as follows:
   200Mhz  5v 0.80A =3D 4.0 watts  2.2v Geode GXI
   300Mhz  5v 1.10A =3D 5.5 watts  2.0v Geode GXI
   166Mhz  5v 1.20A =3D 6.0 watts  2.2v Geode GLXV

   This is correct: Short description:
   We have 3 standard versions of =84Cool Roadrunner II" (PC/104-Plus).
   1. S-104-CRR2-VE200 (4 Watt)
   2. S-104-CRR2-VE300 (4,5 Watt)
   3. S-104P-CRR2-K300 (5,5 Watt)

   Legend:
   104 =3D ISA-Bus
   104P=3D ISA-and PCI-Bus
   CRR2=3D Cool Roadrunner II
   V =3D external VGA Controller with 2MB internal SGRAM for LCD and VG=
A
   E =3D 10/100 BaseT Fast Ethernet Controller
   P =3D PanelLink
   S =3D Sound I/O
   T =3D TV OUT Controller for the direct connection to a TV
   K =3D Contains =84V=93, =84E=93, =84P=93, =84S=93 and =84T=93
  200 =3D 200MHz CPU Speed
  300 =3D 300MHZ CPU Speed

8) Are these figures the Maximum or Typical consumption?

   Maximum (depends of the OS a bit)

Lippert sent me a bunch of attachments with more info on the TV Out=20
features, including assembly code patches. They also send me a bunch
of PDF files with info on Geode GX1 Processor, CS5530A Companion,=20
C&T 6900 video controller, and schematics for a TV out adapter=20
cable.=20

I now have all of the specs for TP400 and Cool RoadRunner II. I will
be doing a feature-by-feature comparison between these and PCM-5822
so they can be compared more easily. Both TP400 and CRR2 look very=20
nice but both are quite expensive relative to PCM-5822.
