Apricot LS550(430FX models)

Change clock：enable with jumper settings

FS0, FS1(FSB settings)

 

FS0	FS1
Close	Open	60MHz
Open	Close	66MHz


 
BF, BF1(Multiplier settings)
 

BF	BF1
Open	Open	x1.5
Close	Open	x2.0
Open	Close	x3.0
Close	Close	x1.5

 
Setting example:Pentium-200MHz
Set to 66MHz FSB ------- Only jumper FS1
BF,BF1 set to x3.0 ---- Only jumper BF1
I've checked working MMX-Pentium at 200MHz.

For MMX-233MHz, (x1.5) settings work (x3.5).
But BIOS only shows below 200MHz.
