[CentOS] Re: getting device to boot from thumb drive

I have created a custom kernel as I needed to add floating point emulation to the kernel. I used the command below to create my initrd:

mkinitrd --preload=ohci-hcd --preload=uhci-hcd --preload=ehci-hcd --preload=ext3 --preload=jbd --preload=scsi_mod --preload=sd_mod --preload=ata_piix --preload=libata /boot/initrd-2.6.9-67.ELmsgnet.img 2.6.9-67.ELmsgnet

When I copy my vmlinuz and initrd to my ext partition of my thumbdrive I get the initial grub screen, centos starts booting, kernel starts uncompressing, I get the following:

Unable to locate RDSP RedHat nash version 4.2.1.13 starting sda: assuming drive cache: write through sda: assuming drive cache: write through

Then it just sits there. Nothing else happens.

What might else I need to get this thumb drive booting? I compiled the kernel in i386 math emulation is the only items I changed. I started with i586.

I edited the /etc/fstab and instead of a label I change the first entry to: /dev/sda1 / ext3 defaults 1 1

Now it boots much further. I get to a point where is says "mount error 6 mounting ext3" However from above I have preloaded ext3, I see the Loading ext3 while its booting.

I see scsi0: SCSI emulation line I see sda: sda1 sda2 (which are my 2 partitions)

Then I see: Creating root device Mounting root filesystem and mount error 6 mounting ext3.

Not sure what I am not doing as my mkinitrd command above preloads ext3 What am I missing?

Thanks,

Jerry
