REQ: How to patch NT driver file .SYS

[ZeRoN]

Dear ALL,

I've try to cr@ck some program thats have its own NT driver file .SYS

I must have to change some bytes (eg. JXX -> NOPs)
this method work fine with all .EXE, but not work with .SYS

It may have self CRC or something like that, I don't know!

Could anyone advise me?

THX IN ADV.
Regards,
ZeRoN

Its OK now, I've use PE-Explorer to re-calculate PE checksum. (.SYS is a PE file)
