Dear all,

we have some old stations ( without hard disk) but with a special ethernet card and eprom with etherworks3/turbo configured with mop boot : when they boot, they contact the vax, and it send a image file, and download a windows 3.1 and some other exe applications.

my problem is that old pc are very old, and we need to use them again for 2-3 years : is there a possibilty to emulate a mopboot ? emulate a false mac address is not a problem but for mop....

do you have any idea ?

tahnk you !

Most PCs can be configured to do a PXE or TFTP based boot is their BIOS settings.

PXE is a superset of TFTP and some other protocols.

OpenVMS/IA64 8.3 and later allow setting up a PXE BOOT server which may or may not require the Infoserver utility that can be enabled for it.


I do not know if those instructions will work for using an Alpha as a PXE server.

Any VAX/AXP/IA64 system with TCP/IP installed can be configured as a TFTP server.
If your PC will TFTP boot, you probably just need to configure that image into the TFTP server.

Most Linux systems can have the cobbler program installed to be a PXE server.

Some PCs have an internal USB socket or you can get adapters to to connect up a USB drive or sdcard as an internal hard drive.

I would look for an sdcard adapter that allows you to set the device read-only.

You can set that as the boot drive, and then you have to figure out how to get it to boot your OS.

NetBSD has a MOP daemon built in. It's incredibly simple to set up and configure, and it could run on anything, such as a Raspberry Pi. Perhaps that'll work for you.

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
