13.1 Please see the FAQ on the main PsiLinux page
(FAQ) for other possible FAQ.
13.2 Q: Which Psion 5MX model do I need (16, 24, or 32Mb)?
Any of these models will work fine, although there seem to be lingering
problems with getting all of the memory recognized on the 24MB machine. It is
best if you have the 32MB model, of course. A compactflash card is essential
if you want a full system.
13.3 Q: How come after PsiLinux boots up the text is faded so as to be illegible?
This problem arises in the 4bpp mode of the framebuffer depth - some of the
color mappings are not yet quite correct. For now change the color depth by
fbset -a 2bpp, and perhaps modify your startup scripts to
do this automatically. See the "Setting the Framebuffer Depth" subsection.
13.4 Q: My disk gives errors when my psion wakes up from sleep mode, or
At present, the ETNA code (which governs compactflash) in psilinux is
evolving. ETNA documentation has been lacking. Mainly, however, the
various brands of compactflash cards behave differently in psilinux -
some cards work very well, others work poorly or not at all. This may
have to do with the type of controller the manufacturer put in the
card (e.g., Hitatchi, Toshiba, or ??).
You can try backing up your system
on a notebook computer, and then reformating the
card, which has been known to be helpful.
You can also search for bad blocks on the disk. Some bad CF cards,
have been "fixed" by running
on it with destructive write test for each partition. Then use the
*.badblocks file to mkfs. The command you might use is:
badblocks -o 96mb_sdb1_12mb.badblocks -w -p 2 /dev/sdb1
In one case, badblocks failed on a USB CF adapter, but then worked
with a CF to PCMCIA adapter on a laptop.
13.5 Q: Can I have a dual boot system (EPOC and linux)?
Sure - format your compactflash card to have whatever
space you need for EPOC and the remainder to be the
ext2 filesystem. On the EPOC filesystem (fat16) install
ARLO and the kernel, and whatever EPOC programs/files etc.
you want to use (in EPOC I use the addressbook and the
alarm clock mainly, as well as other things like Solun, a
planetarium type thing). I have a 128MB compactflash disk
with 32MB reserved for EPOC and 96MB for linux (of with
about 40MB is the operating system.)
You will have to reset the clock everytime you boot between
linux and EPOC, but a system is being developed that will
do this automatically.
Note that you will be able to access the fat16 partition
from linux, but not the ext2 partition from EPOC.
13.6 Q: How come when I turn my psion off for the night, it turns itself back
There are two possible reasons for this. The first is that if you
touch the 5MX's screen slightly it will turn on again - so you may
be inadvertently touching the screen as you close the psion. The second
reason is that you may have the infrared port running - did you kill
the irattach process after you last used it? The IR is always searching
for something to connect to, and a false hiccup will cause the psion to
wake up again. You should turn off IR when you are not using it, because
it uses considerable power.
