![]() Why won't it work with MSDOS.SYS? Does MSDOS.SYS only work for when it's on your hard drive and not a floppy image? Certain dos utils didnt run right though. I also tried with LZ DOS you kindly provided but still hangs. I have tried 7.1 aka WIN98 and whatever i put it in the MSOS.SYS it hangs after Starting. I meant to say W95 MSDOS.SYS not DOS 6.22. Here's a free trick to make the DOS screen change colour by editing COMMAND.COM and searching for MOV BH,07 and change the 7 to one of the below. 1 for when the key is pressed called the make code and another scan code called break when depressed.į8 Inactive Make 42 Break C2 Active Make Break E0 42 E0 C2 Does anyone have a clue on assembler or knows anything can try and help me find the right opcode to patch. I went through the code and 4200 looks suspicious, comes up a few times but too many times. INT9 INT21 and INT16 seem to be the ones. I also looked up what interrupts use the keyboard. I looked up the keyboard scan codes and hex 42 00 is coming up on F8. I thought if i can patch IO.SYS to disable F8 and the rest of the function keys. This has no effect on W98 disk and actually makes it hang. This can be done with 6.22 by editing MSDOS.SYS and putting 0 on certain Boot. If i use less version of DOS there's no cd prompt. I need to use W98 as it uses JO.sys to prompt to insert CD. ![]()
