3640 router crash fixed w/ iomem, have a question

Hey guys, I just got to experience my first router crash you could say...

3640 w/ 128/32 memory and NM2E2W was in a loop booting up saying "SYSTEM INIT: INSUFFICIENT MEMORY TO BOOT THE IMAGE!"

A cisco solution had me remove the NM and if it booted up (which it did) to do:
conf t
memory-size iomem # (# is 5-50 percent of DRAM to allow flash to use, i set it to 10)
After i did that I powered it off, inserted the NM and everything is working now.

My question is: is there a default iomem value? I read that using the command disable SMART INIT so I was just looking for a little more info on the command default. I checked my other 3640's but i couldnt find it anywhere...

Thanks,
Dan

    Interesting. This 3640 was powered up and working prior to issuing that command? Why did it boot before without the command but now CAN'T. I would like to know what caused this behavior... icon_scratch.gif

    If you don't set the mem size then it will automatically calculate an iomem value.

    What version of IOS are you trying to run anyway?

    that's what I'm wondering too! Yes it's been working for a few days and it started while i was using it in a lab setup today.

    IOS c3640-jk9o3s-mz.124-10a.bin

    i have it on 3 3640's
