Biostar M5ATD Motherboard w/AMD K6-2 CPU
The subject CPU requires a Core Voltage of 2.2V and an I/O Voltage of 3.3V. The motherboard manual shows this combination of voltages for the Cyrix 6x86L / 6x86MII with the jumpers set the same as shown to provide 2.2V and 3.45V for the AMD K6-2. E-mail to Biostar has produced no response as of this time. Have I discovered a misprint in the manual? Is it safe to install this CPU on this motherboard?
Are you sure there isn't a setting for the 2.2V and I\O 3.3V
If I am not mistaken you just leave JP15 open and you have the I\O voltage set to 3.3 volts
What motherboard is this for sure?? you said M5ATD, I can only find that model up to the M5ATC which has the settings you need with the jumper JP7 with pins across 3&4 and JP15 open (no jumper)

The motherboard is M5ATD and jumper settings as they appear in the manual are posted at "www.biostar.com.tw/English02/06_manual/m5atd.htm". The jumper settings for the Cyrix CPUs at 2.2V / 3.3V are JP6 VID0 open, VID1 closed, VID2 open and VID3 open. These jumper settings are identical to those shown for the AMD K6-2 at 2.2V / 3.45V.
Dear Goody,
Just visited AMD's site to see their list of approved Biostar boards at
http://www1.amd.com/K6/k6mbl/index/1,1054,,00.html
and the ones which passed muster to date for K6-2:
M5ALA (rev 1.1) 266 to 350 MHz
M5ALA (rev 2.0) 266 to 450 MHz
M5ALC (rev 2.0) 266 to 450 MHz, plus K6-3-400
Good luck

Thanks to all for the pertinent comments and to MATTCEI for data confirming my suspicions about the manual and to ramcomp for the info from the AMD site. I now feel confident to give it a try.
