0x0001817c..0x000181f4 size 0x78-bytes: This seems to be the bootrom error screen font gfx data. This begins at the exact end-address of the crt0 code, the rest of the protected boot11 code begins at this end-address(0x000181f4).

* 0x0001817c..0x000181f4 size 0x78-bytes: This seems to be the bootrom error screen font gfx data. This begins at the exact end-address of the crt0 code, the rest of the protected boot11 code begins at this end-address(0x000181f4). To extract the font gfx data from there, the 30 dwords at this address need to be converted to big endian. The correct resolution (when displayed as raw) is 32x30x1. The bootrom font looks very similar to [https://robey.lag.net/2010/01/23/tiny-monospace-font.html this font].
