Hi, I think I somehow destroyed my initrd. When I try to boot there are messages : kernel (hd0/2) /boot/vmlinuz root=/dev/hda3 vga = normal [linux-bzImage, setup=0x1400, size = 0x1078c4] initrd (hd0/2) /boot/initrd [Linux-initrd @ 0xdfbd000,0x22deb bytes] uncompressing Linux ... invalid compressed format (err = 1) -- System halted I still can boot with the safe settings, so how could I restore the initrd from the standard boot ? Any pointers welcome. I was trying to install a Firewire disk, so I tried to install the ieee1394 modules at boot, and ran mk_initrd. This didn't work so I removed the ieee1394 entry and again ran mk_initrd. Everything still worked OK, but at one of the next boots fsck checked the disk (and found errors), and I think the problems started after the next boot. B.T.W. I'm running 8.1. -- Met vriendelijke groeten, Koenraad Lelong R&D Manager ACE electronics n.v.
