Last time I did this with the 32-bit ppc code you'd drop this into arch/ppc/boot/prep as "ramdisk.image.gz" and then make zImage.initrd.
I did the initial port of Linux to the 43p/140 but I did it as chrp so it fit rather well with Mandrake. But paulus decided to redo it as prep (the hardware defaults to a "prep" memory map even though it does have OpenFirmware). So this will make it into a strange animal. If you grab the zImage.initrd from arch/ppc/boot/prep/zImage.initrd you might be able to boot it into the Mandrake installer. Stew might be able to build this for you (Stew?). Once you get this zImage you can boot it from the open firmware prompt. Hit F8 as the machine boots (after the keyboard icon appears during the self-test). You'll drop to a "0> " prompt. Now type: 0> boot cdrom:,zImage rw root=/dev/fd0 load_ramdisk=1 ramdisk_size=36000 text assuming the zImage is at the top of a cdrom (standard iso9660 format -- note that IBM calls the device "cdrom" while the mac uses "cd"). The rest of the args are stolen from Stew's yaboot.conf. You might have to use root=/dev/ram3 -- dunno. Stew might be able to test this technique on a mac with a chrp zImage with initrd to make sure the args are right. Unfortunately, yaboot won't work. This isn't a big deal, other than it is very nice for booting vmlinux's and add initrd's at runtime, not to mention selecting alternative kernels. Last I tried this I got stuck in fdisk, but Stew got that fixed. But at that point I lost access to my 140 :(. Hope this helps a little. Once you get through an install it should work provided you can find a kernel that will boot ok on the 140. Make sure you have a supported video adapter, also, and put it in either slot 1 or 2. The best video adapter for the 140 was the GXT120P (a 2MB Matrox mystique). It may not be worth doing this unless someone is already trying to get Mandrake to work on other prep hardware. -todd BTW, a "hack" approach would be to install on a mac, tar the entire contents of the drive and drop it into an fdisk partitioned scsi drive. Move that drive to the 140 and boot it up. Scary, but you might be able to see it run :).
