Modifying Windows Cd Boot Image

[HardDriv'n]

Hi.

I've attempted to modify some files from a boot image I've extracted from my Windows install disc.

Everything runs as to be expected, except for the 'setup from cd' option.

Here are the setup files. Could someone tell me what I did wrong?

My main attempts here were to add a ram-drive option, and also include USB drivers support.

-EDIT-

All of this code is a 'copy & paste' hack from multiple sources, so I actually don't understand some of it.

I just want an easy way to reinstall quickly, with everything in one place in case I have to restart...... again.

Also, not having a floppy drive on my other PCs is a motivator to include the floppy tools ram-drive, so I can run everything from the cd.

Nevermind. I figured something out.

1. Extracted the boot image from my orginal Windows 98 SE install disc, using the final 'ISObuster' freeware edition.

2. Used the trial version of 'WinImage' to resize the 1440kb floppy image to a 2880kb floppy image.

3. Used 'WinImage' to add the files extracted from 'EBD.CAB' into the floppy image, and then deleted the cab.

4. I used the command line tool 'MKBT' to extract a bootsector from my Windows 98 emergency boot floppy.

5. I used the same 'MKBT' to add that bootsector into the resized floppy image.

6. Rebuilt the untouched Windows disc structure with the freeware 'IMGBurn', after selecting the floppy boot image in emulation settings. (Added UDF support while at it)

Done.

"a ram-drive option, and also include USB drivers support."

Windows 98 SE come with USB drivers support!

we need to know the make of your Computer so we can tell you how to get to your Setup Utility on your Computer BIOS!

for you need to go to Computer Setup Utility

And Enable the USB controller

And windows 98SE will see the usb ram-drive afterwords!

Remainder Windows 98FE don't come with USB drivers support!

A wee bit late for posting, but...

@HardDriv'n - It's possible (provided you understand the BAT files) to combine the EBD method with the CD Boot method for RamDrive. Search MSFN for more alternatives to Ramdrive.sys as well (better freeware methods). One place to look is the "more than 1gb memory"(?) thread. Also, the EBD.CAB can be "re-cabbed" with only the programs you actually want and then extracted to the created RamDrive thus saving space in the IMG file.

@hottext - re-read the first post. The Boot is Pure DOS-mode and not Win32-98SE, so DOS-mode USB drivers are necessary (as has already been incorporated). :;
