Afair my model has Bios 1.12 version. Not sure if an update to 1.14 is possible. That FreeDos model seems pretty strange and not widely sold.

How much ram is usable after upgrading to 8 GiB? I own an E330 as well and i can only access 3.2 GiB on arch64 using UEFI (legacy bios completely disabled). can you post the output of dmesg | grep -i memory ?

No problems here. But I'm using legacy BIOS and old style partitions.


-- Many thanks for the information! You are missing 1 GB of ram because of memory mapped IO just like me. The E320 does not have this problem.

By the way hibernate works here (edit grub cmdline, edit mkinicpio.conf as explained in the wiki)


For memory mapping see there at that page the comment at the buttom: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS029304
