Recently upgraded our Cisco 4948 with no apparently problems. The switch appears to be opperating fine. However when you enter "show version" it still shows the old IOS. When you enter "show config" or "show running-config" it shows the upgraded version. How do we correct the "show version" command to display the current IOS?
I noticed you entered the word bootflash:/ with a slash before the filename. This could be where I'm missing the boat because it doesn't show "bootflash" when I use the auto complete feature. I have been entering #boot system flash cat4500-ipbasek9-mz.122.53.SG1.bin and I haven't been entering a forward slash! I will give it another try once you confirm my reply.
You shouldn't need the / but from memory i don't think it matters either way. Don't use the auto complete feature at the moment, just type it in manually and make sure you save it to memory. You just need to confirm it is in the running config with bootflash in the string before you reload the switch.
