Please recommend a way to edit the IO.sys file.

[MaMister]

What is the best way or software to remove some texts in the io.sys ? So that I can make the boot disk without those text.

[Swordfish]

you can edit msdos.sys and config.sys, both text based, and that too with Notepad its easy that way.

io.sys is a binary file you shouldn't edit it with any text based editors and should always be left alone.

you will most probably mess up your boot files if you try editin io.sys with notepad or some text based editor.

From dos promt (not windows) >

eg..


attrib -h -r -s -a c:\io.sys.

Edit c:\io.sys

Attrib +h +r +s +a c:\io.sys

Thanks, I am just trying somethings on this weekend.... wonder some people can do it and named their own bootdisk....

[crossedup]

Sounds cool, you going to change Microsoft to MaMister?

Got any links so we can see what your trying? Got a pretty good idea but come on, share. :D

for editing binary files, you can use frhed (FRee Hex EDitor) from www.kibria.de/frhed.html (http://www.kibria.de/frhed.html)

My favorite has always been Hextreme.

The homepage seems to be down but i just downloaded it from that link and it is the same thing

maybe i am missing somethin, can anybody care to explain how you are going to edit a binary file.

the io.sys file, if you open in it in a hex editor it looks somethin like the following.

check the attachment.


i dunno how you guys can interpret the whole stuff here.

:rolleyes:

There will be some text that you can view and change.... like Windows to swordfish....;)

[RampageIII]

Just make sure to copy or back up the file befoore messing with it.;)

Used to be a program that made those sort of changes for the common man but I can't remember. But the hex editor will certainly do it.

[fancyf]

I did that once with fdisk... renamed Fdisk options to F@ncy's Party
:)

If I remember well I used the DOS based Disk Edit of Norton and also you need to keep the same # of caracters, less chance of messing up that way

[herosrest]

This is a useful way to protect against malicious code.
Rename fdisk, format etc...

Be careful out there. ;)

[Swordfish]

cool...i have never done that kinda things with io.sys.

thanks for the info guys....

maybe if i can get hold of a 98 system then i can also do some r&d's.;)
