Math Emulation-How?

Math Emulation-How?

Post by Rob van Vli » Mon, 05 Dec 1994 11:10:04



I have a problem installing Linux (slackware distribution) on my 386:

I don't have a math coprocessor, but Linux thinks I have. Result: system hangs.

Is there any way to tell Linux that I don't have a coprocessor?

Please mail.

Thanx,

Rob

Did you check you Motherboard for switches and you BIOS for Co-Pro setup
options? And then a 387 is soooo cheap now-a-days ... just buy one!

Alternatively you might want to check the kernel code and start hacking ...
get into the Linux spirit.

Ah come on, don't leave him clueless. Rob, when booting Linux hold down
the Shift key just before you see the LILO prompt. Then, at the lilo
prompt, type the name of the kernel image (TAB gives a list) and
add the word "no387". That will turn on math emulation no matter what.

1. Linux install/boot diskette kernel with math emulation?

Hi.

Linux newbie.

I would like to install Linux on a machine that has no math
coprocessor; it's an old 486SX. Which means I need math emulation in
the kernel. To install on such a machine, I need install diskette[s]
whose kernel also has a math emulator.

Most distros these days seem to assume that machine has a math
coprocessor. So, your advice needed. Which distro's install diskette
kernel has a math emulator in its kernel?

Install diskettes I have tried all hang or crash. I have tried: Red
Hat 7.3, FreeBSD 5.0, tomsrtbt, and Vector Linux 3.2 (using the
i386ide boot diskette). At least Red Hat gave me a message why, the
others just reboot or hang.

And I am a newbie: I dont have another machine to rebuild a kernel,
which is why I am looking for a distro with an install diskette kernel
already built with a math emulator.

Hopefully, I need not go back to a very old build of a distro.

Any suggestions?

Thanks!
