I'm not sure what you mean by "ramdisk install on ... SATA disk".
If you want to just try kexec, take look at your current boot
configuration file, e.g., /boot/grub/grub.conf. For example, on my F7
system, I have the following stanza:
title Fedora (2.6.23.15-80.fc7)
root (hd0,0)
kernel /vmlinuz-2.6.23.15-80.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.23.15-80.fc7.img
I could boot that as follows:
kexec -l /boot/vmlinuz-2.6.23.15-80.fc7 \
--initrd=/boot/initrd-2.6.23.15-80.fc7.img \
--command-line="ro root=/dev/VolGroup00/LogVol00 rhgb quiet"
kexec -e
Alternatively, to boot a diskless kernel/initrd, I might use
kexec -l vmlinuz --initrd=initrd.img --command-line="root=/dev/ram rw"
kexec -e
