I have that exact same model Arista .

Is EOS64-4.28.13M the latest in the 64bit 4.28 train?
Is anyone able to share it?
The info I've seen from Arista indicates that they don't recommend EOS64 on older platforms like these due to its heavier memory requirements and the fact that the extra addressable memory provides no benefit for what this generation of switches would be used for. I suspect you can run EOS64, but I haven't been on my 7050SX2s, and haven't run into any real limitations with the 32 bit code.

Edit: Arista's recommendations for which platforms are best with EOS 32 vs 64 bit are here:

What about that cannot remap PCI memory region? Does that means I don't have enought memory? And why is sg module missing? Everything worked without errors on EOS-4.28.10.1M. Could be problem with 64bit version?

I would appreciate it if anybody could send me/point me at the latest firmware for an 720XP-48TXH-2C-S and CCS-720XP-48ZC2. Thank you!

Hi there!
Could anybody share EOS 4.13.16M for DCS-7124SX?
As I figured it's the latest EOS for this switch. Is I mistaken?
