Weird Bootdisk Needed

[rabbit]

I need a floppy bootdisk that says "boot from the CD-ROM", but I'm not sure where to get one that does that, and I'm not exactly sure even what to search for...

[edit]
Newby sucks at giving me the bootdisk.

That's a tricky problem, because the BIOS doesn't really know how to work a CDRom. 

I'm not exactly sure what your eventual goal is, but the common way is to put a small Linux kernel (vmlinuz or whatever) on the disk and boot that, somehow.  There's lots of guides to doing that.

Hm.  So basically what I want to do is boot to vmlinuz and then mount the CD-ROM and then run the installer?  I'm still not sure about the last part, but I'll find out soon enough.

Okay, I've got the bootdisk, but when I dd the image to the floppy, it doesn't work right.  I guess that's because I don't know WTF I'm doing.  How do I dd it?

I probably have no idea what's going on here, but would MSCDEX and sys a: do the trick here?

Why was this trashed? He answered rabbit's question as to where it needs to be written on the floppy. He didn't say the specific dd command, but he did give information.

...none of which was helpful.

[rabbit]

Wow...that was useless.  I don't think I'd be much of a ....me...if I didn't know where bootsectors go.  They go in the middle, right?

[Joe]

You do know that a bootsector can call another bootsector, right? And that said bootsector could be in the middle, right?

That wouldn't actually be a boot sector, though.  It would have code related to booting.

A boot sector is called by the BIOS.
