RE: Is possible Linux on flash memory?

[Gregg C Levine]

Hello from Gregg C Levine
It should work indeed. However, I've got a strange series of problems that might be related to my distribution's choice of versions, and I'll post the script output here in this message. However, it will be a long one.  I think some of these problems might be related to the distribution you chose, Steven, whose is it, and what's the version on it? Mine is Slackware 9.1, which came with those versions of tools.
(Script output follows.) 
That's the versions of my GCC, and binary tools.:

Is possible Linux on flash memory?

[Steven James]

Greetings,

It looks like the IDE stuff is the result of things changing in the
linuxbios source since baremetal was checked in.

I'll have to look at the usb problems. My setup was with gcc 2.95. I'll
try it on my newer gcc 3.2.2 (RH 9 ish) and see what's up.

G'day,
sjames

However, it will be a long one.  I think some of these problems might be related to the distribution you chose, Steven, whose is it, and what's the version on it? Mine is Slackware 9.1, which came with those versions of tools.
