freebsd-hackers@,
Anyone seen 4.8-RELEASE running on a real 386 processor (not a 486, 586 etc) ?
I have a 386 that runs 4.7, dmesg below, both GENERIC & my own kernel;
But it wont boot 4.8 { either generic or my own config } compiled on my
other 4.8 box. I tried making with & without /etc/make.conf
CFLAGS = -m386 -march=i386 -msoft-float -mcpu=i386 -O -pipe
COPTFLAGS= -m386 -march=i386 -msoft-float -mcpu=i386 -O -pipe
I tried the /kernel copied from a 4.8 cdrom to hard disk (no cdrom
drive on the box). I tried 4.8 boot floppies (to prove its not
something wrong in hard disc /boot) Every 4.8 kernel crashes during boot -s.
This 386 box is no bigger than a book, so worth persevering :-)
"SX 33" is written on chip, though dmesg reports "DX".
I recall 386 support was dropped in 5.0, but presume not dropped in 4.8,
( I don't see any signs in /usr/share/mk comparing 4.7 & 4.8 )
The 4.8 cdrom /[A-Z]* files say i386 is still supported.
I removed the only card in the box (a 3com ISA ethernet jumperless) -
it still wouldnt boot, so put ethernet card back in, as not the problem.
I compiled a kernel with ddb, Results copied by hand as no serial for
remote gdb.t present
Ideas or solutions anyone ?
