Unfortunately I'm out of town until about November, so I'm unable to dig out the manual from my dismantled retro stock pile. Those codes are only important if the mobo goes mad. Which in this case is quite often. 🤣. Only joking. Your BIOS is about 6 months old. I think the beta BIOS is about May 2002. I'm sure you can download the final BIOS from the net somewhere (dated about April 2002 I think), although it isn't the beta version. It'll still work with a mobile barton XP-M CPU. Grab a 2400+ rated version. You can either "knife it" and get access to up to 18x multi, or probably a better option is to play around with increasing the mobo's FSB. One of my Epox Pro boards actually doesn't have rotten caps - gasp! Well, two look a bit iffy near the RAM slots, but I can increase the FSB to 169 and the mobo doesn't go insane. I get very good benchmarking scores.
Some tips to get this beast working: use a good PSU with lots of juice on the 5V rail. Eg 35-40 Amps. If you're using a powerful graphics card, consider using a second PSU for it - even if it's just for your initial testing to make sure everything's working OK.
I found out that an AWE32 doesn't work all that well in the ISA slot, but an AWE64 does work well. The AWE32 makes lots of pops and crackles, but the AWE64 is noise-free.
There's a "fan made" chipset patch thing you can install which helps out with stability. I think it's called George Breese latency patch.
