Xtender Diagram Confusion
Posted 07 August 2002 - 12:07 PM
When I arrived at the webpage to begin my venture, I was dissapointed to find that the first 2 arrowed points on the diagram were left blank, in other words, they had indicator arrows, but with no numbers on??????
so I say to myself WTF!!!! and sink into a state of depression as I dont seem to be able to get any help
I did find some alternative diagrams, but these seem to be designed with the SMT version in mind and also seem to differ quite a bit from the intended (original) diagrams I was given.
I cant seem to find anyone who can tell me for sure what to do? - I sent an email to xbox-scene yesterday, but still have got no reply, I guess they are busy, but when your all revved up with no where to go that doesen't help any
Finally, if you look at the "original" diagram, there is a point that say "Link to point 32" - does this mean that I put a link wire to between there and point32 on the diagram ???
So if any 1 can help in here, I would be really grateful indeed

|The two unused points are only two additional Adress-Lines for the Chip (with which you can access everything beyong 256 kByte) ... so they are NOT needed.|

Do you know for sure that this is the case or like me are you speculating?

I can go with the top one being point 1 but the second cannot be 2 ?
I'm starting to think I should forget this chipping lark

The original diagrams are still at Lik-Sang if anybody needs them...
Might be a good idea to archive them yourself while they're still out there...

Amid the abscence of any helpful replies over the past few day's as no-one seems to know, I spoke to the dealer where I bought the chip, only to find that the guy who does his chipping has "Never" used one of these baby's so they offered to swap me for the smt / pcb version of the chip
It just keeps getting better
At least there are tried & tested diags for that one & I can go ahead and do the job without sweating too much
But.....what a pain in the ass it has been

since the Xtender uses 8bmit FLASH roms this points are for the 2 MSB of address bus.
if you'r using 2Mbit FLASH bios ie. 29f020 or 29F002, then you don't need to connect those points.
you only need to if you use 29F040 or 29f080 , for the first (wich is 4mbit) you need to connect just one of them (point 2 of xtender diagrams to A17 of the chip) , and of the second you need to connect the both of them (points 1,2 of xtender diagrams to A17,A18 to the chip)
