3750E flash memory

Hello,

I've got a 3750E switch which should have 64M flash memory, but it only shows me about 55M by show version command.

Does anyone know where the 9M memory is? What is used for?

Thanks.

3750E#dir flash:
Directory of flash:/

You can upgrade your 3750E to IOS version 12.2(58)SE or 15.0(1)SE.

Some should go to the NVRAM.  Enter the command "dir nvram:".

3750E flash memory

Thank you.  Yesterday I was able to manually extract the tar for 12.2(58)SE2.  Still would like to resolve the issue with the flash memory.  We use LMS to do code upgrades, and when LMS cannot find the desired flash, the job fails.  For this switch it was looking for 64meg.  I think this can be manually adjusted within LMS, but wonder where the memory went.
