Yes LCDinfo supports HD44780. You could try other LPT settings in the BIOS.
Also i'd triple check the wiring and check for proper grounding.
Which wiring scheme have you used?

ok the wiring scheme i used is from www.electronics-lab.com
http://www.electronics-lab.com/projects ... ndex2.html
but i grounded pins 8-15 (i think thats what i did :P), and even before i grounded them i got the same problem... my display is a wintek(?) wm-c1604m says HD44780 compatible compatible, my wiring is ok i checked like 4 times :P

{edit} my bios doesnt have an option for epp ONLY :( maybe a windows setting?

Use this one:

whaddya mean 'i think i grounded 8-15' 8O
pin 18~25 on the LPT connector should be grounded, also make sure you have the portdriver installed, see that Smartie site.
