<P>
&nbsp; Hi,<BR>
&nbsp; &nbsp; I want to write some data at the end of the SMBIOS structures present \
in my system's BIOS. I could sucessfully read and parse the SMBIOS structures in the \
BIOS, but could not write any data into it. All attempts to writing into the nvram \
memory by memory mapping it using ioremap or by using device /dev/nvram ended up in \
vain as the data saved was not being retained across reboots. <BR> <BR>
Can anybody help me out by letting me know how can I write any data into the NVRAM \
which contains BIOS.<BR> <BR>
Thanks,<BR>
AKSharma<BR>
