HwInit of Power Mac 6100 ROM is incorrect

ROM:
version: 077d.20f2
checksum: 9feb69b3
md5: b40998471e33d802b350f699127e36df

Configfile-1 says 
```
HWInitCodeOffset=BASE+0x330000=HWInit               # [44] Offset of base of Hardware Init Code
HWInitCodeSize=0x00010000                           # [48] Number of bytes in Hardware Init Code
```
but the extracted file is only 0x200 bytes.
