Help ezoflash v4.5

[europhon]

Hi all, I find very interesting the programmer ezoflash v4.5 and so I decided to make one.
Once done, I have a problem which is as follows:

1º ezoflash 4.5 When I connect to power supply LED light up D1, D3 and D5 simultaneously, without connecting the LPT port, not sure if that's normal.

2º ezoflash 4.5 When I connect to the LPT port, turn on the program Willen, and connect power supply and perform hardware test, I have no voltage on the following points:
A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, A16, A17, A19, A20, A21, A22,
I have set the BIOS to ECP and no voltage at all these points, however if I put the BIOS in ECC, I have always voltage on all these points, but turn it on and turn off in willem software.

Please if anyone can help me.
Best regard

1. Yes . It is normal. Parallel ports signals by default are logic high , they turn on programmer voltages. Start Willem SW and all port pins reset to log.0. I recomend start Willem SW, and then connect programmer and power supply.
2. Are you able turn on/off , change adress voltages levels ? Is it in ECC mode ?
Recomended BIOS LPT mode Normal or EPP. In mode ECC sometimes problems with certain signals , affect programmer Vpp,..
