Hi all!

Is there a Problem with a ASUS SP3G and a AMD DX4-100? I'll try this combination
since several days, but I haven't found the correct jumper settings. The BIOS always
detects an INTEL DX2-66 and LINUX says this too (33,22 bogomips instead of 49,...!).

Does anybody know the correct jumper settings???

So long

-----------------------------------------------------------------------
CPU SL Selector: JP30-JP32 (Intel 486DX4 is SL-Enhanced CPU)

JP30 1&2
JP31 1&2
JP32 1&2

-----------------------------------------------------------------------
CPU Internal Clock Selector: JP33

JP33 leave open

-----------------------------------------------------------------------
CPU Type Selectors: JP34-JP36, JP38

JP34 2&3
JP35 1&2
JP36 2&3
JP38 leave open  (this jumpter is by itself, above the CPU)

-----------------------------------------------------------------------
Intel DX4 Voltage Selection: JP40

JP40 2&3 (selects 3.45 volts)

-----------------------------------------------------------------------
CPU External Clock Selector: JP18 & JP20
I'm not positive, but I think the DX4 uses the 33Mhz clock.

       25Mhz   33Mhz
JP18    2&3     1&2
JP20    2&3     1&2

I hope this helps.  I've still got some things to figure out before I
even try to boot mine.  Maybe you can help me.

Are you using the on board SCSI-2 controller?  If so, I know to set
the board to be a terminator (I'm not using an external SCSI devices).
But how do you terminate the other end of the chain?  I'm just using a
single SCSI hard drive.

Second, do you use the keylock feature, using the lock mounted on the
case?  I've got the lock, but it is only a two wire connection, and
anohter two wires for the power indicator.  The motherboard has a five
pin connection for both functions, so I'm not sure what to do here.

Let me know if you get it up and running.

set it up for standard dx-33 system but instead change jp36 to 1-2 instead of
2-3..   dont forget that it wont come up in the bios msg right.. but it works
right.. also set it up as a NON-SL cpu

After a few calls to ASUSTEK in CA, here is the solution:
-Reason:The motherboard came out before the AMD 3V chips.
-Set the jumpers to the following (undocumented):
    Jumper:    Setting:
    -------    --------
      34         2&3
      35         1&2
      36         1&2
      38        open

-The BIOS now says that I have a 486DX2/100 but the guy said that
it is because the BIOS doesn't recognize AMD 3.3V chips.  A future
BIOS update will fix the problem.
