In case of use of a underwritten
material as the guide to action, the author means
precise performance of the reader that he is going
to to make, that can receive and whether it is necessary
for him in general.
Part
the first. Brief. For those who understands nothing,
but wants and is not afraid.
The main moments - numbering of lead-out of the
processor.
Рис.1.
Socket370 - нумерация, сигналы, вид со стороны ножек
процессора.
I.e., to receive " correct arrangement "
(for readout of number of a leg), is necessary to
turn the processor (or a card / adapter) legs to itself
(details downwards for a card / adapter), and two
"cut off" corners (key) to arrange at the
left. Then the left bottom corner will be the beginning
(absent leg A1), on a vertical - letters from A up
to AN, across - numbers from 1 up to 37.
The main moments - types of sockets Socket370
(PPGA / FCPGA / FCPGA2).
PPGA (Plastic Pin Grid Array).
Processors with socket PPGA have the characteristic
plastic case with the metal cover closing a crystal.
All processors Celeron on nucleus Mendocino (under
them he and was developed) with frequency 300-533MHz
have it. Also with him have been compatible (i.e.
the very first processors Celeron on nucleus Coppermine
533/566MHz with a voltage of a power supply 1.5V (in
spite of the fact that they are made in case FCPGA)
will correctly work without any remaking).
FCPGA (Flip-Chip Pin Grid Array)
Has the characteristic plastic green case with an
open crystal. All processors Celeron on nucleus Coppermine
with frequency 533A-1100MHz and Pentium III on nucleus
Coppermine 500-1133MHz have it.
FCPGA2 (Flip-Chip Pin Grid Array 2)
Same, as well as FCPGA, only the crystal is closed
by a copper cover (heat sink). All processors Celeron
on nucleus Tualatin with frequency 1000A-1400MHz (on
sale appeared and 900/950MHz though in official documents
such are not mentioned) and Pentium III on nucleus
Tualatin 1000-1466MHz have it. Also in such execution{performance}
(FCPGA2, i.e. by and large FCPGA with copper sheet,
and the same distributing, as at FCPGA) met rare Pentium
III on nucleus Coppermine 933-1133MHz and Celeron
on nucleus Coppermine frequency 900-1000MHz.
Remaking.
Case the first, the most simple - remaking PPGA
for support FCPGA of processors Celeron Coppermine
533-1100MHz).
(Для поддержки Pentium III Coppermine есть некоторые
тонкости - см. раздел для "интересующихся"
и "продвинутых")
(For support Pentium III Coppermine there are some
subtleties - see section for "were interested"
и "advanced").
For that that has earned processor with Coppermine
nucleus in old PPGA a motherboard (adapter) it is
necessary to make only two actions - to isolate a
leg of processor AM2 (unsolder, to break out, etc.)
and to connect the crosspiece of leg X4 and AH4 (to
solder the crosspiece on a motherboard, an adapter
or accurately to roll up a delay on the processor,
that, the truth, is essentially more difficult).

Переделка PPGA в FCPGA.
Case of the second, remaking of FCPGA-card/adapters
for support of FCPGA2-processors Celeron and Pentium
III on nucleus Tualatin.
In the given section, we shall consider the most
simple case remaking under Tualatin processor - on
FCPGA it is necessary to establish a card / adapter
Tualatin, i.e. then other processors (for example,
Coppermine) there will not be inserted. If there is
a desire to receive " a universal socket "
- see sections see section for "were interested"
and "advanced".
So, for remaking it is necessary - to isolate pinout
AJ3 and AN3 (unsolder from a socket, to break out
on the processor to put on isolator, etc.), to short-circuit
among themselves G35 and G37, and also AM34 and AK36/AL37
(see fig.).
Рис.3.
Переделка FCPGA в FCPGA2.
Except for these simple actions there is one difficult
moment - pinout AK4. She, on the one side, needs to
be isolated from a socket, on the other side, to submit
on her voltage Vtt (easier - from the nearest leg
AN11). Here it is possible to act differently: accurately
to drill contact AK4 and then to lead there the crosspiece
from AN11, to put on on AK4 isolator, having inserted
in him the crosspiece from AN11, etc. If not it is
a pity the processor (or a leg already break;) it
is possible to draw a track a special current-carrying
pencil (or such as that). Here - business of imagination
of everyone, the main thing - confidently
to isolate AK4 from a socket (since "ground"
there is initially dissolved, i.e. "0"),
having submitted thus on him the necessary voltage
(i.e. there should be "1").
Case the third, remaking of cards / adapters PPGA
for support FCPGA2.
The given case can have many subtleties therefore
can demand more detailed studying (see section for
"were interested" and "advanced").
In the most simple case - it is necessary is simply
banal to repeat the above described remaking in PPGA->
FCPGA, and then FCPGA-> FCPGA2.
