I've been using elementary OS Luna 32bit for a year in my Acer Aspire 9412WSMi, no problem. I can install it at any time. But I cannot install Freya 32bit.
I've used both bootable DVD disks and USB sticks. Even if I use the Smart Boot Manager (usb image, with unetboting) from sbm.bin disk image I get a message on my screen:
[1.649601] Corrupted low memory at c000c6cc (c6cc phys) = 00000108 [1.649682] Memory corruption detected in low memory
Install stops soon. I've updated BIOS from V1.05 to V1.24 from Acer.
