I'd say defective FLASH. The 4500's are pretty forgiving. I have installed 2500 and 3600 series in a pinch, with no repercussions.
Take turns removing each 8 Meg stick. It may just be one of them. Don't lose heart, 4500 series FLASH is very cheap right now. I think I paid around 14.99 for (2) 8 Meg sticks on Ebay last month. All the best !!!

When the router booted up, observed following error message : % Invalid chip id 0xFFFF detected in System flash. Setting System flash access to READ-ONLY. Other than that the router was able to boot to 'router (boot) >' prompt. I entered 'copy tftp flash' command, got following message: Address or name of remote host [192.168.0.10]? Name of file to copy? c4500-a3js56i-mz_121-9.bin Copy c4500-a3js56i-mz_121-9.bin from 192.168.0.10? [confirm] Checking for file 'c4500-a3js56i-mz_121-9.bin' on 192.168.0.10... [OK] dev_iopen: System flash not writable. - Was this because of wrong type of flash ? - How can I change the flash to 'Writable' ? Thanks in advance for any feedback. _________________________________________________________ Do You Yahoo!?
