I wouldn't go so far as to call this an interim release, as there are
quite a few known rough edges, but in order to give the rest of the
code some much-needed exposure, everyone who's interested is invited
to try and run it.

GSOC students, both while applying and while working, are expected to
run this release, or a newer version if available.

Take a look 3.1.4 at
http://www.minix3.org/download/
the direct link to the ISO is
http://www.minix3.org/download/minix3_1_4_ide_r4203.iso

The SHA1 is 114839e1a8d9af39184fc5e25fc5958970d0952e.

some rough edges that are known are are being worked on that come to
mind are
  . slower; due to vm implementation, this is still to be optimized
  . no AHCI support; need to change to IDE mode in BIOS on new
hardware
  . on new hardware, DMA sometimes doesn't work (at_wini panics); set
'ata_no_dma=1' in boot monitor

On the plus side, it should work out-of-the-box with vmware and qemu
(and presumably bochs). And other major (no more chmem hassle; no more
unnecessarily large X server) and minor improvements.

Please share your experience with us in the group, if you find a new
bug a bug can be filed in the bug tracker.

You can expect more of these snapshots in the near future, and until
the next official release.

Enjoy!

The booting issues with QEMU 0.9 should be gone. QEMU 0.10 works fine
also; it never had the problem. If you're using QEMU or KVM, don't
forget to set qemu_pci=1 in the boot monitor.

We'll have to investigate the VirtualBox Lance problems further. If
you're a VBox user, you can try to restart the Lance driver (as Matthias
Schmidt mentioned). It may work, but maybe not.

Enjoy that Minixy VM goodness (pun intended),

Today i installed Minix 3.1.4 and now i am trying to compile
/usr/src/lib with "make all-gnu".
Probably something is broken here 'cause gcc fails to compile
/usr/src/lib/sysutil/profile.c with a lot of errors like this one:

profile.c:253 error: request for member '_' in something not a
structure or union.

It should be a little problem with the u64_t type definition....

So far no errors besides that user error, :)

When i try to do "mtools format /dev/fd0:" i get this error:

fd0: disk interrupt timed out
fs: I/O error on device 2/0

It is not an hardware problem, it works on Minix 3.1.3 r3066
I will file this bug in the bug tracker.

However, AFAIK Qemu does not emulate a Lance network card by default
but a Realtek card. Why did you pick Lance?

'format -v /dev/fd0 1440' doesn't work for me, it fails with the same error.
I will try to debug the floppy driver and i will tell you something more, ok?

however, i found two new problems:

1) "make hdboot" fails because of errors in framework/audio_fw.c

DEV_READ undefined
DEV_WRITE undefined
.....
unknown selector REP_PROC_NR
illegal use of selector REP_PROC_NR

and so on....

2) I did a clean reinstall of Minix 3.1.4 and a terrible system panic
(hard reboot) occurred,
you can reproduce the problem (i hope) with the following sequence:

- Reinstall Minix 3.1.4
- Choose the "R" option (Reinstall Option, leave /home untouched)
- Install all packages (packman 'all')

System panic occours when packman will try to "Update GCC Libraries"

Everything work fine if you choose the "F" option (Full Reinstall Option)

Let me know if that works.

Also, the installer did not check the disk for bad sectors, it did do
this in previous versions.

Kudos for getting the NIC working properly under VMware without the
need to fiddle with it.  ;-)

The librarys are installed with the make install all-gnu, however the
GCC binary is not actually compiled by any method, packman, the easy
updater or by manuall compile.
Unfortunately I don't have the time to devote to tracing the cause.

i'm trying to find this bug that prevent me to use the floppy drive.

However i need a little help:
Should i look for the bug only inside floppy.c or there is some other
component that can be involved in this behaviour?
