GRUB configuration with 3 disks (Linux RedHat 7.2)

[Emmanuel Viennet]

I'm trying to install GNU/Linux RedHat 7.2 on my machine:.
the disk configuration is:
 - IDE 0:  disk 0 (master), zip drive (slave)
 - IDE 1:  disk 1 (master) 60Gb
 - SCSI:   disk 2, cdrom, cdwriter, ...

The new linux is installed on disk 1 (ie /dev/hdc).

After RedHat install and reboot, the pc displays
"GRUB" and hangs (no error message, no prompt).

I can boot from the floppy.

Does GRUB support booting from the third IDE disk ?

Any suggestion ?

Thanks,
Emmanuel
