I managed to unexpectedly snag an AMI Enterprise III a couple weeks ago when I met up with a guy to purchase a CRT. I've been messing with the board ever since. It has a somewhat rare RTC, so I had to do a battery mod to even get it to boot. That succeeded, but I still got a checksum error when it boots. Regardless, I was able to install DOS and run some programs successfully.
This morning I decided to flash a new bios and it seemed to initially work (flash beep codes seemed correct), but on restarting the bios dates did not change. I did some card swapping and now I get a beep code that corresponds with "bios needs replacing". I'm not sure what triggered the bios error, but my guess is that the flash actually failed and needed additional power cycles to manifest.
I'm 90% sure I just need to get a new bios chip and flash it- the checksum error I was initially getting was probably an indicator that the bios had issues to begin with.
Can anyone recommend a flasher and compatible chips? Keep in mind I'm a complete noob with this type of issue.
