I have the same problem with the 
bootopie-v0.8.4-rc3-h2200.tar.bz2

this is my startup.txt (copied from instructions)

set KERNEL zImage
set MTYPE 341
set CMDLINE "root=/dev/hda2 rootdelay=5 console=ttyS0,115200n8"
bootlinux

This is the fdisk of CF

root@malo:/mnt# fdisk /dev/sdc

Comando (m per richiamare la guida): p

Disk /dev/sdc: 1045 MB, 1045094400 bytes
255 heads, 63 sectors/track, 127 cylinders
Units = cilindri of 16065 * 512 = 8225280 bytes

/dev/sdc2               3         127     1004062+  83  Linux

this is the list of /dev/hda2

brw-rw---- 1 root root 3, 2 2006-07-24 21:42 /mnt/sdc2/dev/hda2

I change the fstab as described in the guide:
root@malo:/mnt# cat /mnt/sdc2/etc/fstab

/dev/mmcblk0p1  /media/card     auto    defaults,sync,noauto,noatime,exec,suid

this is the error I got when i try to boot using haret.exe:

Waiting 5sec before mounting root device...
pccard: PCMCIA card inserted into slot 0   
pcmcia: registering new device pcmcia0.0
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "hda2" or unknown-block(2,0)
Please append a correct "root=" boot option              
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

I dont know what I may try. It seems to me that the /dev/hda2 is a block device.
Can yoou help me?
Thanks
