[OK] Up until this point, I conclude the following. You did this from RX boot mode with a TFTP server presumably on a local segment or directly connected. The IOS accessed the TFTP server and verified a copy command would execute. Your flash is also empty (has no IOS on it).

[yes/no] yes > > Exception: Jump to zero at 0x537FC (PC) The SYTEM error message of "jump to zero" is somewhat cryptic in explanation from the command reference. Here is what it says: "Jump to Zero Error This type of error often occurs when the Cisco IOS Software tries to execute data instead of code. Most of the times this is caused by a software bug, but if the symptoms clearly point to a hardware failure, consider the possibility of a defective CPU hardware (see Troubleshooting). " Frankly, I would not want to be thinking it was time to replace a CPU. When looking at the troubleshooting procedure for this, it seemed to be pretty straightforward: "Basically, the problem is either hardware- or software- related. Some types of crashes clearly indicate a hardware or software failure, but others are not that obvious. In this case, common sense is your best ally. If a router has been operating properly for months and suddenly starts reloading every 20 minutes, the problem is most likely a hardware issue. If it starts crashing after a configuration change, then it is probably software-related. For hardware problems, try to identify the faulty card using the Memory Maps, the show region command for more recent Cisco IOS. Software versions, or common sense (for example, if the problem appears after the insertion of a new module). You can also perform additional tests (using the same module in another slot, or another module in the same slot, and so on) to identify the faulty equipment. For software problems, upgrading to the latest version of your Cisco IOS Software release train will get rid of all known software issues. If the router still crashes after the upgrade, it may be due to a new bug. In this case, contact your Cisco technical support representative and provide as much information as possible (Troubleshooting Router Crashes)." The methodology I would use to solve this problem is the following: 1. First and foremost, what changed? You have flash without an IOS. Was there an IOS previously there, or is this new/different flash? If the flash is different/new, read on. 2. Since I noticed that you had a boostrap of 10.2(5) below, I went to the Cisco 2500 Boot ROM Features page and noticed something that might be relevant to your situation. Take a look at what is supported for your version of boot code: "10.2(5) First implementation of 10.x boot ROMs on mask ROMs, which works in 2501-4 for the first time. 10.2(5) has a bug that causes it to not work on the 2509-12 (it will not load an image from flash)..." More importantly, look at what is supported in the next version of boot code: "10.2(7a) Support for AMD flash SIMMS, a 4Mb SIMM made from AMD 29F080 and an 8Mb SIMM made from AMD 29F016. Allows you to mix AMD and Intel flash SIMMs as long as they are the same size." I am wondering at this point what type of flash you are using? 3. You may want to take a peek at these commands: show flash chips and show flash errors The first command will indicate to you whether you are using AMD for your flash, or mixed Intel/AMD. If so, your router may be having fits, based upon the version of RX boot code you are running. You may also want to take a look at the second command to see if you are getting errors with your flash. Keep in mind, these errors *may* be induced by the issue of an old boot rom. If this is the cause of your problems, or you wish to eliminate it as a potential point of failure, you may wish to upgrade your boot roms. I would *not* recommend getting the most current version from Cisco. There is a bug on that version that you might be concerned about: "11.0(10c)XB2 A Cisco 2524/2525 with T1 CSU/DSU will not boot when the line is configured for superframe (CSCdj22485). The Cisco 2505, 2507, and 2516 may go into a boot loop (CSCdj40137)." It would appear that your best bet is to get a boot rom of one version less than the most current, namely 11.0(10c)XB1. If you need one of these(set of two roms), let me know. I will send it to you for the cost of shipping. > > System Bootstrap, Version 5.2(5), RELEASE SOFTWARE > > Copyright (c) 1986-1994 by cisco Systems > > 2500 processor with 16384 Kbytes of main memory > > > > I am able to "copy flash tftp". > > When the system boots/reboots i get this... > > > > ERR: Invalid chip id 0x80B5 (reversed = 0x1AD ) detected in System > flash > > Loading cisco2-2500 ... [timed out] This error message seems to be pointing to incosistencies in your flash. It is entirely possible that you may have a bad flash SIMM. My recommendation would be to first attempt to get a good version of RXboot code and then see if the problem resolves itself. Before you even attempt to do a copy (after putting in current boot roms) just try erasing the flash. See if it will do it with out complaining. If so, I would then attempt to upgrade your IOS to the 12.x code you wanted. HTH, Paul Werner p.s. I don't believe the squeeze command is supported in class B flash file systems(which the 2500 belongs). I could be wrong. ________________________________________________ Get your own "800" number Voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=4253&t=4253 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
