I had the chance to spend a few hours installing plain 7.3 on a Motorola
PowerStack Series E with 64MB RAM and a 604 CPU.
Not a whole lot of time, but I noticed a few things up to now that may be of
interest as I couldn't find comments anywhere on these topics.
- While I could boot the first CD, the machine froze after the message
"Uncompressing" when trying to set up the RAMDISK. Couldn't find a way
to get around this. Is the PReP CD boot kernel known to be broken?
This was due to a last minute change to allow booting on a 43p 140, it
broke PReP MTX and similar...
You might be able to boot with "noinitrd" into the installed system.
- I used some very old (6.4?) install disks I still
had somewhere to boot a kernel
far enough to get to the 7.3 CDs. Didn't have much success putting the kernel
available with 7.3 onto floppy disks. They are apparently larger than 1.44MB.
The files on the ftp server will fit on the floppy:
- The PowerStack in question was AIX formatted. The
install process will not
allow partitioning and will not(!) issue an error message. I used a separate
virtual console to manually pre-partition the disk to a DOS empty state to
be able to install the system. Took me a while to figure that out.
This bug in fdisk was fixed later.
dd if=/dev/zero of=/dev/sda count=42 will also help.
- Debian documents a "bootargs" PPCBUG
variable which apparently the SuSE
kernel doesn't support. I hacked the kernel content for the root partition name.
Would be nice though if it supported bootargs.
This is a generic bug, I dont know if it is supported at all. At least
my MTX+ allows me to set that, but the bootloader doesnt know about it.
- /usr/X11R6/bin/sax doesn't exist. Well, sax.sh
does, but that's not what sax2
tells me. Anyway, XF86 V3/4 apparently isn't set up to support the Cirrus chipset
as both sax and sax2 freeze the machine with a black screen eventually.
Interesting enough, X itself starts up in 640*480with FBDev on top of CLgen,cfb8
but sax/sax2 won't ever. X freezes up the machine *very* easily on just a few
mouse clicks. I guess for now I have to avoid X.
Do you have a CL5446? Mine can not do more than 1024x768 or I will get
garbage after a while. You need to generate your own modeline, or use
fbset -a 1024x768-75 -depth 8
- "halt" doesn't. The machine will
reboot and doesn't stop. Actually, no PPC
kernel ever halted on the PowerStacks that I tried. Wonder why.
Known bug, no idea how to tweak the registers...
$ man clone
Main feature not yet implemented...
