# ree

Extract BIOS ROM extensions

includes the tool `fontdump` (to extract the fonts from your video bios roms)

make sure you can read /dev/mem (be root)

`chmod +x ree.sh`

`./ree.sh`

or use the c version (much faster, and does checksum on the rom extension)

`make # or gcc ree.c -o ree`

`./ree`

will scan your system memory, address c0000 - f0000 in 512 byte steps for

identification of rom extensions (55,aa), if found it will calculate

its size (byte after id, multiplied by 512) and saves that to a .rom file.

ported to shell from the pascal version of 1997

original (dos/win9x) version is ree.exe and ree.pas in ree.zip

## BIOS CMOS / NVRAM

Probably most interesting is this:

`cat /proc/driver/rtc`

`cat /proc/driver/nvram`

and its raw data

`xxd -g1 /dev/nvram`

## note

as most system bios are bigger than 64k nowadays (128k or 256k) and them

are only 64k memory window reserved, they are not dumped completely.

use flashrom for complete dumps.
