In the *BIOS +setup* program for lenovobios, you can specify that the system will use +one or the other (but not both). + +Libreboot is known to work on systems with only the Intel GPU, using +native graphics initialization. On systems with switchable graphics, the +Intel GPU is used and the ATI GPU is disabled, so native graphics +initialization works all the same. + +CPU paste required +================== + +See [\#paste](#paste). + +</div> + +<div class="section"> + +Flash chip size {#flashchips} +=============== + +Use this to find out:\ +\# **flashrom -p internal -V** + +[Back to top of page.](#pagetop) + +</div> + +<div class="section photos"> + +MAC address {#macaddress} +=========== + +On the T500, the MAC address for the onboard gigabit ethernet chipset is +stored inside the flash chip, along with other configuration data. + +Keep a note of the MAC address before disassembly; this is very +important, because you will need to insert this into the libreboot ROM +image before flashing it.
