Haiku raw image C/H/S specification

Forum thread started by Erstnzi on Fri, 2008-11-14 19:47

Hello, I'm a new comer here.
I want to try Haiku and how it does things, but I'm afraid of installing it on a new partition with the dd tool. Two months ago, I lost my 50gb partition playing with a faulty partitioning tool(and my own mistake) on winxp, so I really don't have the courage now... And I find virtual machines too slow. so I'm trying to boot the disk image as a disk drive with various tools without succeeding until now, and I thought knowing the heads and sectors per track of the raw image would be a good thing.
May someone give me this information please?

Haiku is very usable in Virtualbox and Vmware, but if you still want to use hardware, you could ask in the haiku mailing list for the dev Sikosis to help, thats if another doesn't help you here first.

Re: Haiku raw image C/H/S specification

Modern disk controllers, operating systems and bootloaders use Logical Block Addressing, LBA which is a simple linear addressing scheme. The Cylinders/Heads/Sectors addressing scheme has been obsolete for more than a decade. Thus a raw disk image makes no assumptions about the numbers of heads or sectors which might arbitrarily be reported by your hardware via compatibility interfaces.

Most likely if you think you need CHS values you are doing something completely wrong.

You will probably get better help if you follow one of the existing guides to installing Haiku e.g. to a USB stick and report whatever problems you encounter.

I did some more search...

Initially I was trying to boot the raw image using grub4dos(this seemed the best for my situation), a grub derivative, but it seems that it will not boot from an image file unless the OS is a real mode one, like MSDOS.
I can get the haiku booting screen by chainloading it, but that's all, then I get an error message saying there're no bootable partitions. So I don't think it will be possible.

Thanks for your help, Nyhus & NHFM.
