Bricked Microstar MS-5124 Socket 7 Mobo

[bogdang]

Hello, does anybody have a dump of the specific bios in the attached photo?
The motherboard is a really strange MSI-MS5124 socket 7 , but with a specific bios version (AMIBIOS AG76).
I have tried with all available bios files from the retroweb - SI3 and SI7 , rom files AG77 and AG79, with no luck.
It reads the image AMIBOOT.ROM from the floppy disk and then just an infinite sequence of 7 short beeps ... until I shut it down (I have waited for enough time, as long as 5 minutes).
