Neoware CA5 X start problems

Hi I have tried to solve this, but I am stumped.

I have a Neoware CA5 booting and fetching kernel/rootfs using PXE.

The error states that the audio device cannot be found.

I have had to force the MM_X_DRIVER='sis' for it to get past the unknown driver issue, I know the documentation say I do not need to do this, but I cannot find a valid list of values. Modprobe shows sis_agp is loaded.

lspci gives

Any ideas ?

Is there any other information required to diagnose this issue ?

Is it time to find another use for this machine ?

The problem is that (1) MiniMyth does not have the sound driver for the sound hardware in that system, and (2) MiniMyth does not know about the PCI product ID for the video hardware in that system. I can fix both of these problems easily. However, whether or not this system can be used as a MythTV frontend depends on at least two things: (1) does it have a powerful enough CPU to decode the audio and video streams and (2) does it have enough memory to run MiniMyth? From what I have found on the Neoware CA5, it has a processor speed of 200MHz and a maximum memory of 256MB. If this is the case, then I believe the CPU is too underpowered and the maximum memory is too little.

Thanks for the followup.

If you want to add them in to the next build I will gladly try it.

The info I found is http://www.parkytowers.me.uk/thin/NeoCA5/index.shtml

It can run DSL linux, but as you say, it may be a stretch to run mythfrontend on it.

I have committed the changes to SVN, so they will be in the 78b2 test build.

I suspect that this CPU will not be powerful enough to decode MPEG2 SDTV resolution video and this memory will not be large enough to run mythfrontend. Of course, the only way to know for sure it to try it.

Sorry, been a while since I had time to sit down and test this.

Using 0.24-1-78 I get

Code: Select all

Dec 12 17:27:31 (none) local0.info minimyth: processing configuration file ...
Dec 12 17:28:07 (none) local0.warn minimyth: 'unknown audio device. assuming audio gain is '90'.
my minimyth.conf file has

Code: Select all

MM_X_OUTPUT_HDMI='none'
MM_X_OUTPUT_DVI='none'
MM_X_OUTPUT_TV='none'
MM_X_OUTPUT_VGA='auto'
MM_X_MODE='800x600'
MM_X_DRIVER='sis'

MM_AUDIO_TYPE='analog'
MM_AUDIO_CARD_NUMBER='1'
MM_AUDIO_DEVICE_NUMBER='4'
How do I need to specify the new driver ?
