In order to better meet the needs of PC users, we have made some improve­
ments in our motherboards. Please make the following changes in you manual.
1) Page 2-7: The sentence, "The exception is you can install one single­
sided > 2MB module in the SIMMl socket"
Page 2-9: The sentence, "The only exception is that you can install a
single module larger than 2MBin socket SIMM 1, with the other sock­
ets empty.
Please change both of the above to the following:
Exception: You may install a single- or double-sided module of
either 4MB or larger in the SIMM 1 socket.
2) Page 2-7: The two sentences, "DRAM Speed: 70ns or faster for 50, 60
or 66MHz external clock. EDO DRAM requires 60ns or faster for a
66MHz external clock setting."
Please change the above to the following:
DRAM speed requirements for both FP DRAM & EDO DRAM:
CPU internal clock (speed written on the CPU): 75, 90,120,150MH2
CPU external clock: 50 or 60MHz
Use 70ns or faster (the lower the number, the faster)
CPU internal clock (speed written on the CPU) 100,133,167MHz
CPU external clock: 66MHz
Use 60ns or faster (the lower the number, the faster)
3) Page 4-11: The note, "Note: The mainboard has no "Turbo" function,
so a switch will not work if you connect one. If you connect a case-
mounted Turbo LED, the LED will light while the system is turned on."
Please change the above to the following:
Note: This mainboard can support the Turbo On / Turbo Off switch
from the case. (Turbo Off decreases the speed of the system.)
