Amibios 8 mod - problem with LPT port

Hello

I have an old Gericom PC with Amibios 8
Could someone mod this bios for me ? 
the problem is that the laptop has an LPT port that does not recognize the device
This device is a programmer based on the 74LS05 chip LPT to I2C
The programmer works on the EPP port in another laptop, but it does not work in this one
I'm not sure but I think the problem is DMA which cannot be turned off
In the BIOS settings you can only change the LPT Port address
Is it possible to modify the bios so that LPT port works in EPP mode ?
