Hi Howard, Hi Howard, I finally got to the A prompt where I typed in format C:/s but when it got to 15% it hung. Did it again and it stopped at 9%; did it again and it stopped at 24%. If I boot without any disk it stops and says NO ROM BASIC SYSTEM HALTED If I boot with a Win98 Startup disk, I get 3 choices, Wihout CD-ROM, With CD-ROM and MOre Info. But then some more files are missing. With my old boot disk, it used to list a bunch of bad or missing files but it went by so quickly that I never did read it. It kept on going and then everything worked OK. Finally pressed PAUSE and read what files were bad or missing. They are: Bad or missing C:\DOS\HIMEM.SYS Error in Config.sys line 1 Bad or missing C:\DOS\EMM386.EXE Error in Config.sys line 2 Bad or missing C:\DOS\Setver.exe Error in Config.sys line 8 Bad or missing C:\SB16\DRV\SBCD.SYS Error in line 9 HMA not available Loading DOS low A:\> Set Blaster =A220 I5 D1 H5 P330 T6 A:\> LH C:\MOUSE\MOUSE Don't know if any of these bad or missing files are causing my format to hang.
