I have one of these laptops and never had a restore disk for it. You might try looking on eBay. Note that all the drivers and utilities are available on the HP site, just go to the support section and look for compaq products. They are likely to be more current than what might be on that disk. Drivers provided support OS thru Win 2000. I have a 300MHz model and although not recommended I recently installed WinXP Pro and am generally satisfied with the performance.
