Bug jumping from bootsect to kernel [SOLVED]

[DavidCooper]

I've just run it in Bochs and it worked straight away.

¡Ya está allí! (I hope that means: "It's still there!") Get rid of the code between the two jumps!

Aún está alli! means that I know it is difficult to learn some thing in spanish but you were very near

It doesn't for me. What arguments are you passing to bochs in order to let me test it. Thanks!

[DavidCooper]

I didn't do anything fancy to run it in Bochs - I just pointed Bochs at the disk image and let it do its thing. It may be that Bochs is running the first of the two jumps incorrectly, because it ought to have a prefix on it and a four-byte address. 234 91 124 8 0 should be 102 234 93 124 0 0 8 0.

Maybe both work. I don't know.

Are you sure you've run the right version in Bochs because it works fine here?

The first jump is correctly coded I think!

[DavidCooper]

It may work both ways equally well. You just beat my edit to my previous post, so I'll ask again. Are you sure you've run the right version in Bochs? It works fine here.

[DavidCooper]

I've just tried it again to make sure, and Bochs tried to run the previous version, but I've tried it again with what is quite definitely your latest version and it worked perfectly.

Ive tryed the latest in bochs and runs ok until bochs freezes... I don't know if it is a bochs bug or my fault. It doesn't run in qemu...

The only issue is the partial second sector where the disk image file runs out.

I'm using Bochs 2.4.5

IT WAS THAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

My friends say that I'm mad as I only have 17 and I've started programming asm myself, but I've met someone that codes machine code! You're great! Thanks! ^^ I'm in debt with you

Wow! I didn't expect that to throw an emulator.

Thanks, but I admire all asm programmers as I think it's much harder than using raw machine code numbers. Anyway, thanks to you and DLBuunk for helping me to improve my asm reading skills.

You now need to edit your first post in this thread to add the word [solved] to the end of the title.

Though maybe you ought to write it to a physical disk and try booting a machine directly with it first...

I didn't do last night because I had to get some sleep for school but I will do now!

Keep improving your spanish

OK! Solved.
