HI all:

I can't find anywhere BIOS-POST codes related to General Software. What mean 0x0d is? It looks like CMOS(Superio) is not running? But I check the FDC37B782, some signal looks good, OSC14M/IOW/IOR has toggled, AEN is low, rstdrv is low, NPOWERON is low, why? Have I make any mistake? Somebody knows anything?

Hi,

Please find attached the manual of GS_Bios that includes the EMBEDDED BIOS POST Codes. ________________ Attachments : Users_Guide.pdf : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006Htrz&d=%2Fa%2F0X0000000aY9%2FYLEAWeXfOustvncDFV2CfN7Lr8Gu_c27ZKqhEZBgtc4&asPdf=false

From my experience with the General Software BIOS, the 0D postcode happens when the CPU can not access the Combo I/O chip. It downloads lots of stuff in it to initialize it, but it will not post any malfunction until it does the CMOS shutdown register test.

So something is wrong with the basic accesses to your Combo I/O chip. Is the base address the same as the one of the demo board?

Base address???

the superio has A0-A15 address line ,so the base address should be decode it by superio, I don't konw what means about Base address? In schematic it same as the demo borad.like this attachfile followed: ________________ Attachments : superio.gif : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006Htjt&d=%2Fa%2F0X0000000aWP%2F.mIfGOtzdmzbsspGkTULm72039V5IFogjXXEdsCxxGQ&asPdf=false

From your drawing I meant the config address. This is the I/O address to turn the device on/off and where all the functions are configured. At power-on the device is off. You have two choices. If the one you choose is different from the one expected by the BIOS, you will get a ''0d'' post code. (doesnt mean that this is your bug, but this is one possibility)

Are you running from the demo board BIOS or are you customizing yours? If you use the BIOS form the demo board, make sure that you use the same configuration resistors as the demo baord.
