It is quick and easy. Around line 8352 make the code look like:
if (p->flags & AHC_NEWEEPROM_FMT)
{
if (sc->device_flags[i] & CFSYNCHISULTRA)
{
p->ultraenb |= mask;
}
else if (sc->device_flags[i] & CFNEWULTRAFORMAT)
{
if ( ((sc->device_flags[i] & (CFSYNCHISULTRA | CFXFER)) == 0x03)
&&
!(p->features & AHC_ULTRA2) )
{
sc->device_flags[i] &= ~CFXFER;
sc->device_flags[i] |= CFSYNCHISULTRA;
p->ultraenb |= mask;
}
}
}
