I am running an 80186 emulator on my Nokia 9290 Communicator that uses
an image of a boot floppie to boot. In order to run linux I boot into
MSDOS with an image of a foppie that has the following line added to
the CONFIG.SYS:

DEVICE=EPOCFS.SYS D:\

This loads my phone's MultiMedia Card (The D:\ drive of the phone) as
the C:\ drive in DOS. EPOCFS.SYS and EREDIR.EXE (used by EPOCFS.SYS)
are both supplied by the maker of the emulator. It is not open source
or verry well supported.Once I am in MSDOS I can boot into ZIPSLACK,
wich is saved on my MultiMedia Card. I would like to use a lomem kernel
to boot strait into linux and load my MultiMedia Card as the root Linux
partition. How can I add in kernel support for the EPOC file system. Is
it a standard file system? If not, how do you think the maker of the
emulator was able to load it in DOS? I Found 0 documentation. If anyone
else out there experimenting with this, please share! THANKS! ...aaron

Linunx can't run on a 80186. It needs a 32 bits processor

I disagree. I'm dont know much on emulating so I could be using the
wrong terminology, but I can boot into MSDOS or a stripped down linux
kernel using what claims to be an 80186 emulator. ...aaron

Maybe you are using ELKS? http://elks.sourceforge.net/ That is a Linux
kernel which is supposed to work on 80186. However, I don't think that
zipslack uses any ELKS kernel by default. What does /proc/cpuinfo say
about your CPU?

Well, you have to explain exactly what you mean for 80186 emulator or
boot into Linux.

Either the emulator is a full 80386 emulator or you can boot, but does
it run?

80186 is a 16 bits CPU and only supports 1Mbyte RAM. It has embedded
peripherals that MS-DOS couldn't handle.

Thank you. How can I figure out what processors XTM is emulating? Is
there a command or method? The description of XTM just says it emulates
a "1980's computer" It said it support 80186 in the readme; it is
possibly not the only processor it emulates. Like I said, the
documentation is really poor. I can boot into ELKS Linux and MSDOS from
boot images but when I try to run slackware it says I don't have a 386.
Thanks for your help! ...aaron

Thats right. Slackware is a full featured Linux distribution with the real
Linux kernel. Slackware uses a Linux kernel compiled for 32-bit 80x86
compatible CPUs. 8086 and 8088 are 16-bit CPUs, 80186 and 80286 are 16-bit
CPUs. The first 32-bit CPU in the x86-family was the 80386.

The standard Linux kernel also depends on a MMU (memory management unit)
which those older CPUs lack.

Porting Slackware to ELKS probably involves alot more work than porting
Slackware to an architecture which is supported by the standard Linux
kernel like AMD64 or s/390.

ELKS is not linux. it's basically a port of linux to early intel processors
on which the standard linux kernel won't run (anything under 386). so the
fact that it runs doesn't mean that real linuxes will run.

I can only suggest you try Minix. It is a Unix like system and some
older versions run on XT. Also the last (2.0.4) has a 16 bits version,
but I think it needs at least a 286.

Maybe fun to try and run Contiki OS on it:

Yes. However some erly versions lockup when running a 32bit OS (Unix) when
having an 387 FPU (math co-processor) installed and doing DMA transfers.
Linux can also run on systems without an FPU installed (which was a
seperate chip with the 386, 486SX and erlier) if compiled with
CONFIG_MATH_EMULATION set to 'y' (the stock Slackware kernel was.)

As uCLinux got merged, mainline Linux 2.6 can run on (some) MMU-less chips.

CMIIW but as i understand it: the 286 /does/ have some kind of MMU. But
the 186 chips don't (which are 8086/88 object code compatible single ICs
for embedded applications.)
