I've received a picopsu, as well as tried using a regular atx power supply.

it seems whenever I try to boot off of IDE, either using a laptop hard drive, compact flash, or microdrive, that I can list the contents of the drives, but as soon as I try to boot a kernel, I get ATA device does not exist or is not responding..

Is there anything else I can to try an remedy this issue?

are you getting this message from open firmware or from the kernel? do you have a custom kernel, or a precompiled kernel? could you post the exact output?

BTW: this setup (booting of a ATA drive) works for me..

this is all in the open firmware, no kernel will boot at all

Try a few reboots before you boot the kernel. At least this helped me with an ancient 2.5" HDD and an older USB HDD. I never had such problem with recent hardware (40+G 2.5" or 250+G 3.5" HDD).

seems I might have more issues than initially thought, a serial terminal, with no harddrives or video cards, shows gibberish... like this:

There seems to be a problem in recent Linux PPC serial console driver. Please try connecting from a PC or using an USB->Serial adapter.

should have been more specific, the system i'm using to connect to the efika is amd64 based...

And what are your communications settings? I just had some troubles, as I did not set up my communications up correctly. From the FAQ:

Q: What are the correct settings of the OpenFirmware serial console?
A:
Baud rate: 115200 bauds
Data: 8bits
Parity: none
Stop: 1bit
Flow control: none

By obtaining a better usb->serial adapter, I was able to fix the console issue, however, the issue remains as far as the hardlocking while losing the kernel and "ATA device not present or not responding"

Just for the record, I'm connecting from linux/amd64 to efika using serial console without any issue. I use minicom-2.2 and debian sarge plus kernel 2.6.18.

What does devalias say? And what is the exact command you enter?

Please give us the output of devalias, as well as the exact command you use for booting.

here's the current status:
Microdrives are not very reliable on efika, some load the kernel, others do not, all however lead to an IRQ 135 error which results in disabling of that IRQ and the root file-system failing to mount as a result. Perhaps the compactflash adapter that I purchased (the same one bbrv used in his blog post and images) is having issues being the only device on the ide chain?

Try booting from tftp instead of USB to get the DI kernel loaded......I had trouble to with 3 seperate usb flash disks.
