Yesterday replaced front O2 sensor which fixed a host of problems, truck running great and check engine light went off. However, upon cranking there is a series of 5 beeps that stops after about a minute. No warning lights, all gauges operating, just the beeps. Any ideas???
5 series of 5 beeps on start up on 1998 Mazda B2500

Probably your air bag system proving out. When you turn the key on, does your air bag light illuminate and prove out? I bet it doesn't - the module will beep 5 times to alert you that the system is operational and your light is out.
can it be easily fixed? (air bag light)
It is a bulb issue most likely in the instrument cluster. It will have to be removed and the bulbs checked and replaced as necessary. That is the first step. Easy - for a qualified tech, not bad. Things can break for the non-experienced person working on it...wiring connectors, trim pieces, and so on. Probably an hour labor and several dollars for each bulb.
