NetBSD/Amiga

[Twiggy]

Thanks for the reply/information.

I get this error on boot:

ep0: wrote 0x7ff to TX_AVAIL_THRESH, read back 0x0. Interface disabled

I'm using a PCMCIA card (3C589D) and the kernel is GENERIC.201703111743Z. Should I attempt to build one with the ep driver, or is it already there and just not behaving?

Many thanks

The ep driver is already in kernel, it just doesn't work because Amiga-specific PCMCIA driver is broken in some weird way. With NE2000 compatible cards (ne driver) it works by some sheer coincidence.

I was supposed to debug this at some point, but life got in the way. Unless someone fixes the PCMCIA driver, ep won't work.

Either one of the pcmio_* functions is broken, or the fact that pcmio_ functions are not defined for word length accesses is the problem... Word accesses are probably needed by ep (while they aren't used by ne).

I would guess so. I had a look into the pcmcia-ep driver this morning, and the error is the result of a 16-bit write operation which reads back as zero.

Seems the Netgear FA411 is also not working on NetBSD? At least it shows up on boot but cannot be configured.

[phx]

Quite likely the same problem as mentioned before. The Amiga pcmcia bus space driver doesn't support 16-bit cards. The FA411 is such a card.

The 3Com 589 PCMCIA works with this patched v9 Kernel:

ftp://ftp.netbsd.org/pub/NetBSD/misc...sd-pcmcia16.gz

Martin Åberg has fixed the bug

Frank Wille has compiled and uploaded the Kernel.

GOOD NEWS!!!

The insights can be read here:

The patch consists in adding the word "swap" at the end of a line of code, I've personally tried!

[avantgarden]

Phew!

Got BSD 9 running on 16 megs of RAM with NO swapping!!

Ok, it doesn't do much, just telnetd over the infamous 3C589 pcmcia card.

I've stripped everything out of the 9 Kernel, even floppy and audio. Now it's 2.4 megs uncompressed!

Also "rc.conf" is a plethora of "NO NO NO NO..."

Two images of this small miracle...




[can't see them, do img need approval?]

Nice! I wouldn't have expected that you can strip down an Amiga kernel that much nowadays. I remember NetBSD 1.x times, where the kernel fit on a single floppy disk and 16MB where even usable for X11.

[avantgarden]

X11 on a floppy!!!

I feel ashamed now...

Interesting times they were, Phx.

The stripping continues! It's a funny task. Down to 1.9 megs.

With a 68030 you also have to use "old" password encryption scheme otherwise login takes 60-80 secs.

From "man passwd.conf":

 localcipher  The cipher to use for local passwords.

                  Possible values are: ``old'', ``newsalt,<rounds>'', ``md5'',
                  ``sha1,<rounds>'', and ``blowfish,<rounds>''.  For
                  ``newsalt'' the value of rounds is a 24-bit integer with a
                  minimum of 7250 rounds.  For ``sha1'' the value of rounds is
                  a 32-bit integer, 0 means use the default of 24680.  For
                  ``blowfish'' the value can be between 4 and 31.  It speci-
                  fies the base 2 logarithm of the number of rounds.

Could you upload it to the zone? Cheers

Hello! You mean upload the kernel?

Thank you

[Twiggy]

Hi,

Yeah, if possible. Or any other means of trying it out with ease. Just curious about having a look. Cheers

[avantgarden]

Of course it's possibile!

https://drive.google.com/drive/folde...4k?usp=sharing

As you may see in "config.txt" reducing size comes at a cost!!

This kernel will only work in A1200 with 68030 + MMU in the ZorroIII slot.

The only recognized drive is the onboard IDE interface, even the floppy is disabled.

The only recognized network card are the 3Com 3C589 / 3C562 pcmcia.

It is built around my machine, so it's not going to be very useful out in the wild!

Thanks for the interest, have a nice day! AG

Could you also Post the configfile here?

That would be nice! Thank you

[avantgarden]

Hello m68k BSD'ers!

In the Google Drive folder you'll find:

[nebsd-micro]  -  The binary kernel

[config.txt]  -  An easily readable version of...

[MYKERNEL]  - ...the config file itself

[rc.conf]  -  "all-NO" version!

[passwd.conf]  This switches off the default super-expensive passwd encryption scheme

All these tweaks allowed me to boot BSD7 on a 2+16 MEGS 68030 MMU Amiga 1200 without swapping!

Of course, any subsequent activity (eg. telnet to the machine) will cause physical RAM to be depleted.

Yes it is slow AF but usable for learning this wonderful OS (second only to AmigaOS).

Very informative writeup:

Maybe the above info (reposted here)

http://mail-index.netbsd.org/port-am...msg008092.html

could help Amiga Debian mantainers to add support for the 3Com PCMCIA cards?

That would be great because the 3Coms' are the most cheap and available in many auction sites.

Thank you very much,
AG
