CMOS defeats solution skill.
1) to CMOS, believe everybody already no longer unfamiliar. Not little to defeating the implied meaning that interprets CMOS password to also have. Here occasionally (Crazy) consults according to his experience the relevant article of elite area will explain how unlock CMOS password:
Show a few structures of CMOS to everybody first:

Afore-mentioned content consulted other data, so not certain and complete correct. In 38H-3BH in these 4 byte, as a result of 39H and 3BH these two byte are 00H all the time, so with respect to skip over, so the key of CMOS password centered 38H and 3AH on these two byte. The password that introduces a bit Award first is regular, award allows to come 8 passwords, the limits of each character by 20H-7FH, 127 when pile up to ASCII by blank space namely. Everybody had discovered most propbably, 8 character should be put in two byte, seeming to be not compressed is no good. Really, award is compressed its, but compress a method commonly, I think Award has additionally add its close think of a way, because be in CMOS room is very much still, wanting to put 8 byte to look do not have what problem, so bare nevertheless password does not have what good more. Normally compress means to nondestructive is compressed, be like Zip, arj, perhaps caustic is compressed, elephantine Mpeg, jpeg. But right so a few byte, these methods do not have the ground of what use force, and has compressed thing, should be OK reductive, press otherwise will press go doing not have what meaning. Nevertheless the method of Award differred, he undertook those who use having superly caustic is compressed not just is HASH algorithm, and this kind is compressed is cannot reductive, he gives out below add close compress a method (the following numerical value, operation all is based on 16 into make) : If have one code, 8, write down for: ABCDEFGH (each limits extraction a cost is 20H-7FH) , press its following and formulary operation: H 4*G 10*F 40*E 100*D 400*C 1000*B 4000*A, press the result by low to tall save: H1, h2, h3, in byte, save H2 the address next: In 3AH, h1 and H3 and in saving 38H. If the password is not worth 8, with this analogize.
