I'm trying to make a standard ide ata flash (32/64 MB) bootable directly in linux, but I always have the same error messages 'GRUB - Hard disk error'.

The bad new is that the same procedure I use works perfectly if using a 'normal' IDE hard disk...

I already try to use the grub-install command, and the command interface (root (hd1,0) + setup(hd1,0)), but with the same results. I also try to force the LBA flag, but nothing happens.


I have no more ideas.

Thanks in advance

It has to do with how the BIOS "sees" your flash card. Each device has a hexadecimal code (i.e., first primary hard drive = 0x080, IIRC) and the BIOS may not be conveying a code that Grub recognizes, or perhaps the mapping file doesn't have it listed. You may be able to do some map commands in your /boot/grub/menu.lst file so that your flash card is mapped to something that Grub will boot.

But that's really just a guess.

The Bios sees the flash card as the primary IDE MASTER hard disk on the target system, but I preare the flash card on the another system where I have a normal IDE hd running a suse distro(/dev/hda) and flash card as /dev/hdc.
On this system I send the grub command to my flash card /dev/hdc1...

In the mapping file I found the /dev/hda and the /dev/hdc

Shoult it be the problem ?

Thanks.

This is the output of the development machine running Suse distro on /hda and the flash card on the /hdc
Thanks again.

Nobody knows more than me about this kinf of boot using grub ?
