F5-221 Reports incorrect memory information in DMI table

[DiscoSi]

In reference to another thread:

viewtopic.php?f=26&t=310&start=10

It appears that the F5-221 reports incorrect memory information in the DMI table using the dmidecode command, compared to the F2-221 which seems to show the right information.

Code: Select all

# dmidecode -t memory
# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.

Looking at the output from my unit it only shows a single available memory bank which is occupied by the built in 2GB memory. It doesn't show the additional expansion slot as either empty or when memory is installed. This isn't a problem most of the time as "cat /proc/meminfo", "top" and "free" all report the full amount. When this becomes an issue is where some software, that isn't specifically written to run on these units, uses the DMI table information (rightly or wrongly) to find out the maximum installed memory.

I find it strange that the F2-221 reports the information correctly in the DMI table when the two units are likely very similar at the BIOS/motherboard level. Is there an updated BIOS or other means for the F5-221 to resolve this?
