1 Hi all,
2
3 I just tried to install Gentoo 2005.1 on a computer with one 9GB SCSI.
4 When booting, I get the following error:
5
6 ~~~~~~~~~~~~~~~~~~~~~
7 Block device /dev/sda3 is not a valid root device
8 The root block device is unspecified or not detected
9 ~~~~~~~~~~~~~~~~~~~~~
10
11 I tried other block devices (dev/sda1 etc) to no avail
12
13 My grub.conf.is as follows:
14 ~~~~~~~~~~~~~~~~~~~~~
15 default 0
16 timeout 30
17 splashimage=(hd0,0)/grub/splash.xpm.gz
18
19 title=Woohoo Gentoo
20 root (hd0,0)
21 kernel /kernel-genkernel-x86-2.6.13-gentoo-r5 root=/dev/ram0
22 init=/linuxrc ramdisk=8192 real_root=/dev/sda3 udev
23 initrd /initramfs-genkernel-x86-2.6.13-gentoo-r5
24 ~~~~~~~~~~~~~~~~~~~~~
25
26 My fstab is as follows:
27 ~~~~~~~~~~~~~~~~~~~~~
28
29 /dev/sda1 /boot ext2 noauto,noatime 1 2
30 /dev/sda3 / ext3 noatime
31 0 1
32 /dev/sda2 none swap sw
33 0 0
34 /dev/hdc /mnt/cdrom iso9660 noauto,ro 0 0
35 #/dev/fd0 /mnt/floppy auto noauto
36 0 0

39 proc /proc proc defaults 0 0
40
41 shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
42 ~~~~~~~~~~~~~~~~~~~~~
43
44 Hope someone can help, as it's getting awfully irritating using a CD-ROM
45 to boot the system (which isn't necessary very often).
