# Boot choices. Uncomment 'set' statements in exactly one section
## Choice 1 - Boot from SD/MMC card
# Have 2 partition on a card:
# 1st - FAT with HaRET executable, this file and zImage above
# 2nd - EXT2 with rootfs tarball extracted
set cmdline "root=/dev/mmcblk0p2 rootdelay=10 console=ttyS0,115200n8 console=tty0"
## Choice 2 - Boot from CF card, setup like above
#set cmdline "root=/dev/hda2 rootdelay=10 console=ttyS0,115200n8 console=tty0"
## Choice 3 - Boot kernel with builtin interactive bootloader (initramfs-bootmenu-image)
# rootdelay is a wait before scanning for the available partitions
# if root= is also specified, interactive selection will be skipped and
# direct boot will happen.
#set cmdline "rootdelay=3 console=ttyS0,115200n8 console=tty0"
## Choice 4 - Boot rootfs image as initramfs (works only for smaller images)
# have a cpio.gz file below together with zImage, no EXT2 partition required
#set initrd "<image>.rootfs.cpio.gz"
#set cmdline "rdinit=/sbin/init console=ttyS0,115200n8 console=tty0"
## Choice 5 - Boot via NFS over USB networking (must be kernel-builtin
# or initramfs-*-image works too)
# 192.168.x.x - Server address (the other side)
# 192.168.y.y - Handheld's address
#set cmdline "root=/dev/nfs nfsroot=192.168.x.x:<nfs_path> ip=192.168.y.y:192.168.x.x:192.168.x.x:255.255.255.0:pda:usb0 console=ttyS0,115200n8 console=tty0"
## Choice 6 - Boot from MTD partition, for devices with lots of flash
# to have both WinCE and Linux there. Note the value of root param,
# that's how it should be, not "/dev/mtdblockN".
#set cmdline "root=mtdN console=ttyS0,115200n8 console=tty0"
