I already have mod BIOS file (.ROM) In working with phlash using DELL bios .exe file with /readgzfile parameter (ex. M1330A15 /readgzfile), I have some stupid questions: 1. Win-GZ (Windows GUI) and Gzip (DOS) is the same result? 2. Case 1 is not the same, how to use Gzip with compress level parameter (1 - 9) Sorry for not familiar to neither Win-GZ nor Gzip. Many Thx for reading.
