Need to make a disk image

Lprogster · Post by **Lprogster** » Tue Nov 28, 2006 4:42 am

I have 2 seperate files, my boot sector and my kernel. The disk image layout needs to be:
1st sector: bootsector
2nd and 3rd sector: kernel

How can I concatenate my bootsector and kernel into 1 image, that I can put on a disk or run in Bochs?

Thankyou guys,
Lprogster

Floppy disk or hard disk image, for bochs or VMware, under windows or linux?

Under Windows you can merge bootsector file and kernel file:
copy boot.bin + kernel.bin image1.img
and then use partcopy to put it on fdd or hdd (infact partcopy doesn't work on NT/2k/XP...)

Thankyou Kataklinger... that is exactly what I needed!

Is there any difference between disk and hard-disk images?

Thankyou lots

partcopy works fine on xp, atleast when copying to fdd.

Yes it works with FDDs, but doesn't work for HDDs. AFAIK partcopy usese direct IO to access HDD which is forbidden under Windows.
