RE: 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.
