Evergreen Performa 1.0 GHz jumper settings
Verolom
multiplier are for this processor. I have my hands on one and am
considering spicing up my old Pentium II.. The board release version is
4.01. Evergreen has nothing on their website.
Your help is appreciated,

Jumper Settings for the Evergreen Performa and Performa III Slotket Cards
In some early releases of the Performa and Performa III upgrades, the
slotket card jumpers are set to factory defaults. Current releases have the
jumpers set according to the CPU installed on the card. The distinction is
this:
* Jumpers set to factory defaults: These settings allow the installed CPU to
signal the motherboard to establish the appropriate CPU voltage and bus
speed.
* Jumpers set according to CPU installed: The settings have been changed so
that the card (and not the CPU) signals the motherboard for CPU voltage and
bus speed required by the installed CPU.
In some cases, having the card instead of the CPU signal for voltage and bus
speed has removed obstacles to booting.
This document provides jumper settings for the range of CPU voltages and bus
speeds used by processors installed on Performa and Performa III slotket
cards.
NOTE: Only jumpers controlling CPU voltage and bus speed should be adjusted.
Jumpers controlling CPU type should be left in the factory default settings.
The factory default settings are listed at the end of the document.
Obtain CPU Data
In order to set the jumpers correctly, you must have information on CPU
voltage and bus speed. In current kits, CPU data are listed on a label
attached to the slotket bracket. This label shows:
* CPU Name
* Cache size (L1)
* Front Side Bus Speed (Maximum)
* CPU Core Speed (Maximum)
* CPU volts
* Manufacture date
Inspect the slotket cartridge to see if the CPU data label is attached. If
it is present, copy down the CPU volts and bus speed data.
If there is no label, then you will have to remove the heat sink and inspect
the CPU to obtain the data. If the CPU is made by VIA, you may have to
inspect the bottom of the CPU to obtain the data. To do this, make sure the
heat sink is off, lift the socket lever, and remove the CPU.
* Examples of CPU volts: 1.5, 1.65, 1.7, 2.0
* Examples of bus speed: 66, 100, 133
Identify Slotket Revision
Two revisions of the slotket card exist. Inspect the upper left corner of
the card to see if the card is Rev 3.0 or 4.01.
Adjusting Jumpers on Slotket Rev 3.0
Hold the card socket side up, with the gold connector edge toward you.
Bus Speed: Find the jumper block on the left side of the card. JP1 and JP2
comprise the 4 pin jumper block (JP1 above JP2). Note that these jumpers are
not labeled. Adjust the setting according to the bus speed of the CPU
installed on your slotket card.
* 66 MHz: JP1 Open and JP2 Open
* 100 MHz: JP1 Closed and JP2 Open
CPU Volts: Find the jumpers on the right side of the card. VID4 is the two
pin jumper above VID3. VID0-VID3 all have 3 pins. The jumper pins are
numbered right to left (3 2 1). Use Table 1 to adjust the CPU voltage
jumpers for the voltage listed on the CPU installed on your slotket card.
Table 1. CPU Voltage Jumpers Settings for Slotket Rev 3.0 and Rev 4.01
Jumper
CPU Volts VID0 VID1 VID2 VID3 VID4
1.50 Open Open 3-2 Open Closed
1.55 3-2 Open 3-2 Open Closed
1.60 Open 3-2 3-2 Open Closed
1.65 3-2 3-2 3-2 Open Closed
1.70 Open Open Open 3-2 Closed
1.75 3-2 Open Open 3-2 Closed
1.80 Open 3-2 Open 3-2 Closed
1.85 3-2 3-2 Open 3-2 Closed
1.90 Open Open 3-2 3-2 Closed
1.95 3-2 Open 3-2 3-2 Closed
2.00 Open 3-2 3-2 3-2 Closed
1) "Open" means the jumper shunt is removed, leaving all 3 pins bare. Do not
leave any "2-1" settings.
2) Pin 3 is on the left, and pin 1 is on the right.
Adjusting Jumpers on Slotket Rev 4.01
Bus Speed: Find jumper block "CN3" on the left side of the card. The block
has 5 pairs of pins, arranged in two columns. Pin 1 is bottom left, and pin
10 is upper right:
9 10
7 8
5 6
3 4
1 2
Bus speed is set with pins 5-10 only (ignore pins 1-4). Adjust the setting
according to the bus speed of the CPU installed on your slotket card:
* 66 MHz: Pins 5 and 6 open, 7-9 closed, 8-10 closed.
* 100 MHz: Pins 5, 6, 7 and 9 all open, 8-10 closed.
* 133 MHz: Pins 5-10 all open
CPU Volts: Find the jumpers on the right side of the card. VID4 is the two
pin jumper above VID3. VID0-VID3 all have 3 pins. The jumper pins are
numbered right to left (3 2 1). Use Table 1 to adjust the CPU voltage
jumpers for the voltage listed on the CPU installed on your slotket card.
Factory Default Jumper Settings
Slotket Rev 3.0:
* VID4 = closed (only 2 pins)
* VID3 = 2-1
* VID2 = 2-1
* VID1 = 2-1
* VID0 = 2-1
* JP1 = open
* JP2 = closed
Rev 3.0 does not have jumpers for setting CPU type, and lacks VID5.
Slotket Rev 4.01:
* VID4 = closed (only 2 pins)
* VID3 = 2-1
* VID2 = 2-1
* VID1 = 2-1
* VID0 = 2-1
* VID5 = open
* CN3: 1-2 closed, 3-4 open, 5-7 closed, 6-8 closed, 9-10 open
Rev 4.01 uses jumper block CN3 pins 1-4 and VID05 to set CPU type. These
jumpers should remain in the default settings shown below:
* CN3: 1-2 closed, 3-4 open.
* VID05: open

... those things are a serious ripmonk. next time, upgrade rationally, eh?

the voltage selector was set for 1.50 V.
I got your point though. Next time it'll be a Duron that fries up, BIOS
that needs updating twice a month, BIOS setup where every other word is
misspelled, 30 MB of additional drivers, some cracked version of the OS
kernel, and a motherboard with so many options that finding the right ones
would take forever. And if they are found, by that time the whole
contraption will need an upgrade again :)
