IDA .sig file doesn't work when target is 16 bits?

IDA .sig works fine when tartget is 32 bits.
Does IDA .sig file works file when target is 16 bits? Only for 32 bits target?
Has someone successed in applying .sig to 16 bits target and
several functions matched?
//thanks

IDA's signature mechanism work well with 16bit code... Just disassemble any Borland's oldie and see by yourself.

Probably:
1) you made wrongly the signature
2) your program contains no statically linked functions belonging to your sig file

Have a look !
