It is normally read only I believe but anywhere can be infected. BIOS, MBR, malware can even jump partitions or HD's

I think the short answer is yes anything in the machine beit RAM BIOS hard drives in short anything that holds stored items / software / instructions can get infected.

Remember that any firmware can be updated and well that means downloading software into it

But I stand to be corrected.

Just Google can viruses infect the BIOS and you will loads of stuff like this one

Yes. Bios can affected by Virus\BIOS rootkit.....

I found one in a "client" pc last year.

Flashing bios in most cases helps,but not always.
