Hallo,
I have written a BIOS for my SC1200 which
does the hardware initialization in
SC1200. Then I invoke the LILO bootloader
which gives control to my linux OS. My
embedded device involves external
pheripherals like Audio CODEC, PCI TV
decoders, Ethernet, TV tuner etc. Is it
necessary to initialize those devices
myself or will the OS takes the control.

Written a BIOS? That's pretty hardcore (at least to me). Out of curiosity, could we see your code?

radhapriya,

Is something not working? The question is a little vague.

"Audio CODEC, PCI TV decoders, Ethernet, TV tuner etc."

Traditionally, no, you shouldn't need to init any of these in the BIOS. Since the BIOS, usually, does not provide functions for these devices. Of course, if you need to do something special, like enable a compatibility mode on the Audio device, then this would be wrong. It's all rather specific. This also assumes that Linux has drivers for all of you devices. Your device (SC1200) should have documentation on all this (system/device init, compatibility, code), and probably has some Linux code you should be using.

YMMV, of course.

Hope that helps,
chris

Please reply

It is a bit strange question, if you are on a level that you are able to write your own BIOS, you wouldn't know about device initialization?

Anyway, it depends on the devices. If they need initialization like, assignment of IO addresses and interrupts, this might be a BIOS issue as otherwise the OS is not able to talk to them.

Compaq BIOS are quite good designed, with mult language menu. Does anyone having a multi language BIOS BIOS on desktop laptop computers?
