Re: developing new BIOS

[Richard Smith]

 I alsoo need the help regarding when to write code for BIOS 
   
 what sequence should I follow 
 I mean which part to init first and which to next 
   
 Ex . 
 1. Enable flat mode 
 2.  init memory 
 then ?? 

Are you following the examples from the BIOS Writers guide on the ST
dev site?  I think it may help with your questions.

developing new BIOS

[Ramesh Chhaba]

Hi All ,

It is not much related to linuxbios.
Actually i am writing initil code for the BIOS for STPC Atlas.
In that code I am probing memory size.
Besides diong memory wriets this code is also changing bank configuration 
and also options like Brust time ,brust length, 

and much more to find out the proper bank and its highest address.

I am debugging this code by running it from DOS :(
I want to know weather it can work from DOS or it must be run from ROM

System generally restarts after getting run this code or just hangs up.
can Anybody provide me help how to debug that code.

I alsoo need the help regarding when to write code for BIOS
