The following PA-RISC machines can be booted like any other box of a different architecture. I must add that this list can change at any time. The best way to get an updated list is to look at http://mkhppa1.esiee.fr/list.html. At this URL, you will know if your hardware is supoorted and how. If you can run PA/Linux via the serial console or via the graphic card. You will also find everything you need there like the PDC firmware updates.
any 712, including 712/60, 712/80, 712/100. You can get X running on them! This box is one of the main target of development. That's why it is so well supported.
newer 715s, including 715/64, 715/100 and all Mirage series.
older 715s, including 715/50, 715/75 and all Scorpio series.
some 720 models are running with the latest kernels but some improvements need to be done.
some 725 models are running with the latest kernels.
some people reported that 735 models are running with the latest iso and external disks.
A180C and similar.
A500 and similar.
BXXX models like B132, B180. These boxes can be used in the framebuffer mode via the Standard Text Interface.
CXXX models like C110, C160.
CXXXX models work with the I/O devices linked to the first IOMMU.
D class is normally working. However, many very different configurations exist in the D-class. As a result, it is quite difficult to make a general statement.
J class is the SMP version of CXXXX models. So, I have to do the same remark.
L1000 and L2000.
The following hardware will work in the future:
L3000 model.
N class.
SuperDome class.
The following hardware won't work:
very old boxes like 705s, 710s, 730s, 750s
E,F,G,H,I class
T,V class
