Comment 33 for bug 413135

The dmi-available-memory script is working fine. I've test it on Dell systems.. as well as the test system I am using now (a Lenovo Thinkpad T61). All report the available memory. The Dell systems only had 2 - 3 gigs of memory. So I have to use my Thinkpad T61 for testing.

For my Thinkpad T61 with 4G RAM produces output:
4194304

While the output of a Dell XPS 13 with 2G RAM produces output:
2097152

Given the d-i installer has no issue think the issue may be further in the logic of ubiquity.
