RH6.2 and Fiasco - l4-hackers

13 Jul 2000

      I'm still not having a great deal getting Fiasco + hello running.  I
opted for the slash and burn technique and reinstalled RedHat 6.2,
downloaded fresh from the cvs server (10 July 2000) and tried to build
from there.
The only snag that I hit that I was not sure about was when compiling
oskit10, the file oskit10/freebsd/src/lib/libc/i386/gen/alloca.S did
not want to compile.  There was, however, a comment in oskit mailing
list suggesting that a fix ("jmp %edx " changes to "jmp *%edx").  I've
appended a script at the end of this mail that make the other small
changes that I needed to build.
Now that it is built, it crashes at boot time:
RMGR: loading (hd1,1)/fiasco/sigma0
  RMGR: detected new-style DD-L4
  RMGR: starting (hd1,1)/fiasco/main -nokdb proto=0x10128c
Welcome to Fiasco!

Any further suggestions?
