And I have video card with "boot=0x043100a4". For this video card no need patch
and no need new kernel and bootId always read correct.

for this video card early I attach log by nvagetbios for info
log by nvagetbios -s PRAMIN >vbios_pramin.rom (64.00 KB, text/plain)

nvagetbios -s PROM >vbios_prom.rom (1.00 MB, text/plain) 
2015-01-29 15:13 

and screen view is correct.

Why does GT520 or GT610 not work like video card with "BOOT0: 0x043100a4" (((
