Answers to the Most Frequently-Asked Questions

Q. Do I need to install Boot ROMs to be 11.0 compliant?

A. No. The Boot ROM upgrade is optional and is not required for Y2K compliance. Cisco's Year 2000 test plan examined all bootstrap

versions used in the Boot ROMs for each compliant platform and determined that there are no date-related issues in them. If a product is listed

as compliant on the Cisco Year 2000 Product Compliance web pages, the Boot ROM version is unimportant.

The currently-shipping Boot ROM on the Cisco 2500 series and the Cisco 2500 Y2K update bundles is version 11.0(10c)XB1. These Boot

ROMs work on all Cisco 2500 models and all releases of Cisco IOS software. As mentioned above, these Boot ROMs are not required for

Y2K compliance and are included as a convenience to customers who want to upgrade to the currently-shipping Boot ROMs. For a detailed

list of fixes and features by Boot ROM version, visit: http://www.cisco.com/warp/customer/471/30.shtml

Q. Where can I find answers to Y2K-related questions?

A. Cisco has a comprehensive Y2K web site that includes the Y2K definition, product compliance summary, and other useful information.

We recommend that you review this web site occasionally to learn about the latest information regarding Cisco's Y2K program. Cisco's Y2K

web site is found at: http://www.cisco.com/warp/customer/752/2000/

Alternatively, you may email Y2K-related questions to year2000@cisco.com.

Q. How much memory does the Cisco 2500 require to run 11.0 software?

A. The following table lists the Cisco 2500 memory requirements to run 11.0 software for select images.

Q. What is the minimum amount of memory ever shipped on a Cisco 2500 router?

A. 4 MB Flash and 2 MB DRAM. Early Cisco 2500s were shipped with either 0 or 2 MB DRAM on the motherboard and either 2 or 0 MB

DRAM SIMMs, respectively, for a total of 2 MB DRAM. As of the end of April 1997, all Cisco 2500s were shipped with no DRAM on the

motherboard and 2 MB DRAM (minimum) SIMMs.

Q. Is there an IP Y2K bundle for the Cisco 2500?

A. IP images for Cisco IOS 11.0 require 4 MB Flash and 2 MB DRAM, so the minimum memory ever installed on a Cisco 2500 is sufficient

to run 11.0 IP software. If you would like Cisco IOS 11.0 IP software at no charge, send an email to: year2000@cisco.com
