problem Modbo 4.0 on SCPH-79001

Hi. Yesterday i modified My slim SCPH-79001 (i think v16) with Modbo 4.0. its a brand new one. i brought both PS2 and Modbo on last week. i have never modd a PS2 before and this is my first time.
so my problem is when i insert a burned DVD Game it says "the disk could not be read" if i insert a burned DVD movie its says same thing. but before modding it played burned dvd movies, and the error massage was deferent when i insert a burned Game dvd (insert ps2 compatible dis or something), but when i insert the Online startup disk (at the moment i dont have any original game) online network connection wizard is loading.

i have soldered all wires except F and CX (diagram its says optional) and BGHI points are very hard to solder. so then i used some thin Coil Wire to solder that points.

please can any one help me to understand what ive done wrong of fix this problem
Thankx

and also cant go to the configuration menu pressing triangle + circle

check your bios points. if you can't access the config menu there's a problem with one or more of the wires for it.

Thanks "Bootlegninja" for ur reply.
this is the diagram i used

can u please let me know wthat are the bioas points are?
thanks again.

Bios points are in "A" area on your diagram ( top left corner ), but on modbo 4 you must connect CX point. It is a clock point, some modchips use clock from the motherboard like Mars, modbo 4.....so if there is no crystal on your modchip you must use CX point. Hope this will help.

Thanks "psxgameshop" for the quick riply. i just fix it. now its working with burned Game but still cant go to the config menu. but im very happy with this. now 1.15AM here.
time to bed.
Thanks you all "psxgameshop" and "Bootlegninja". without ur help i could never fix it.

sorry for digging this thread.. i know its old.

I just want to know how did u fixed this problem..

I have scph-39004 pal and modbo 4.0. the problem is i cant play burnt dvd games but i can access the configuration menu not like his prob.. and also i can play games using HDD with network adaptor without problems..

this is what i use http://sksapps.com/diagrams/ps2/Modbo4/V7V8-usa.jpg

ive already soldered all the points except the H point.

H point is mandatory, it is right from G point. In fact all points are mandatory for modbo 4.

ok i will try that one, i aint soldering that point b/c the diagram tells nothing.

can u point me out whats the meaning of these Letters or link instead if u do?
