Okay, I found out my nbd server had permission issues, running as root now wink

Going back to the first append option from your list I managed to boot into the image big_smile

But now I find out that it's running as i686 while I specifically remember that not working in the past, but now it reports the CMOV instruction. Maybe there was a bug in older kernels which rendered it useless, but changing to the i686 squashfs also just works. (Pretty sure the meltdown/spectre bugs are inaccurate)

Now I've been busy trying to get the default i686 image to do the same thing... Unfortunately the "copytoram=n" option isn't enough for the default boot.

Also using this initramfs it starts complaining about not having /dev/disk/by-label/ ARCH?? when using these options.

Ah, okay... I thought you had created an image with NBD enabled so I could cheat out of cross compiling...

The 8139too driver works great on the actual machine, the vm was just for a screen shot of the NBD hook error messages...

Hi, thanks for your reply smile

Yeah, I got them with busted PSU caps which I replaced (ones without mark). Good thing I've scabbenged all the SDRAM I could find, mostly 256 and 128. (does 512 even exist?) I've always had problems with storage in these, the one DoM I have (in the IDE) also only does PIO4, no UDMA.

Thanks for posting your setup, I've set up my DHCP/TFTP/NBD services, but I'm having some issues with the pxelinux.cfg options.

Been trying quite a bunch of options, but keep running into issues leaving me without a root filesystem.


append ro nomodeset ip=:::::eth0:dhcp archiso_nbd_srv= archiso_nbd_name=arch486iso

This line was based on the third append you have commented out, but should work?
I don't know what your arch486install share contains, or why I get the message about a nbd name/host not being present. (the eth0 message doesn't appear on the machine)

I (still) have stack of these that I just can't throw out... I remember having set them up once on PXE but was already facing issues with Debian Squeeze and was forced to install Lenny. (Did do a three way LACP with 280Mbps LTSP/NBD/remote X)

Now I've found this thread, but I'm not quite sure how to set this up. Should I use the 2018.04.07 iso or compile packages in a vm?

Anyhow, does anyone maybe have an archive of their PXE folder? And send it to me?
