Re: [ros-bugs] [Bug 390] Freeloader Execption: DIVIDE BY ZERO

I had this same problem when developing my bootsector. When I reset the 
bootdrive before I jumped to freeldr the problem went away. I think that 
the first thing that freeldr needs to is to reset the boot drive before 
it moves on.

Why are you wasting your time writing a completely new untested boot sector
when FreeLoader already has a fully working fully tested, stable, and
debugged boot sector? I know, I know - you're going to say that it is a
reverse engineered Microsoft boot sector. There are actually two - one is a
reverse engineered Microsoft boot sector, and the other is FreeLoaders.
Anyone who actually compares the source side by side can see that
FreeLoaders boot sector code is *not* a copy of Microsofts. They are vastly
different. I keep waiting for the auditors to do their job and audit this
piece of code, but they don't seem to be doing it. The point is, we don't
need another boot sector when, as soon as the code gets audited, the
original boot sector will be just fine.

BTW - where can I download your boot sector code? It should be audited just
as much as the original boot sector code, since you've undoubtedly looked at
the FreeLoader & boot sector sources to see how things are done.

Taken from Ged's email ealier:
"First of all, we must take the authors word on whether something needs 
auditing or not."

If you say it is clean, it is good enough for me.  Lets move on.

My bootsector is clean, and it is /highly/ derived from the *FreeDOS* 
bootsector (GPL). If you take the FreeDOS bootsector and mine and look 
at them side by side you will find some striking similarities. I have 
complied with the GPL and put the derivative work under the GPL too. I 
haven't been able to get a dev to look at it yet. If any who fall in 
that category want to, I'll send it to you.

What Brian is saying is, if we already have a perfectly good boot 
sector, what is the point in replacing it?
Brians FreeLoader has been tried and tested and it should be kept.

Ged.

[Magnus Olsen]

I agreed with Ged here.
in this matters.  I do want replace it with u bootloader etihers

My bootsector fits in one 512 byte block and takes in account of file 
fragmentation.

I did talk with him one week back and told him we are not instred in his
