I know, but why the same chip, with the same code, with the same wire, mounted by the same Technician ( myself ), works perfectly on V9 and works not perfectly on V10?

Can you tell me what tipe of hardware you use?
DIP or SMD?
And (i have read this somewhere) you use 54MHz from motherboard with the schematics indicated in 54Mvariant.jpg?
Thanks in advance.
im use own build sx25/48/52 dev board (dip sx28, smd sx48/52) ... and tested both 50M and 54M ... and about V10 differs ... BIOS speed is same ... MX device out current is higher ... looks like V10 problems = GROUND problems ...cause BIOS reading is same as before ...
I will try with SX28DIP and try to connect GND directly to SX28SMD (TitanSx) not to PCB pad.
Sorry but I really don't think it's a ground problem, I'm completely sure about my instalation, Why somebody have ground problems with a V10 and with a V9 no ?
I can confirm that problem is only on MX manifacturer ROM....
There are also v9 with different manifacturers rom .... the one marked with MX have low ( a little than the other ) bootrate , about 70 %. V9 with *ony rom have 100 % bootrate.
i have no problem with this code on any machine ... tested many V9/V10 with MX ROM ... no problem ... im use 5.1V and GND from BIOS (short wire) ... boot rate on V10 with MX ROM (i have one on my desk now) is near 100% for both CD and DVD
i tested on v9 and v10 by simply leaving the install and reflashing the chip:
old code= OK
new code= bad, i dont even think it booted a ps2 game 1 time
i even tried removing the F wire
If what summOne says is true, then maybe, possible, by mistake the code released is not the same as the one you are using lacyg. Or maybe the latest code is more sensitive to improper wiring(lengths) and/or soldering.
By the way, I tried leaving two wires soldered to OSC1 and OSC2(about 14cm) so I can reflash the sx28 , but the mod would not work at all. I guess the 2 wires affected the 50Mhz clock.
It is very important to take care of the lenght of wires with high frecuency and also avoid to overlap this wires with other signal wires to avoid crosstalk.
Make sure don't cross over the optic unit with the ISP connections or chip will not work due to noise from motors .
