Hi,

I know this is a long shot.

Does anybody have legacy AIX 4.1-5.1 device driver source code for this legacy device or PCnet AMD family? IBM did license AIX code out to organizations for customizations.

10/100 Mbps Ethernet TX MCA Microchannel Adapter Device ID: 8f62 -Am79C971 Ethernet chip through an Adaptec AIC960 bridge chip.

Or PCI Ethernet device driver (23100020) as described here:

http://www.mouritzen.dk/aix-doc/en_US/a_doc_lib/aixprggd/kernextc/ethernet_dd.htm

Looking to port this device to x86 based machines.

Thanks,
Ryan

I have an IBM AMD PCnet PCI card in my AMD Ryzen PC.

It uses the Linux pcnet32 driver. Its source code is available for i386
and amd64, maybe this is helpful for you.

I also have a floppy with P/N 93H8201

10/100 Mbps Ethernet Tx MCA Adapter Device Driver for RS/6000

And 93H8197
10/100 Mbps Ethernet Tx MCA Adapter (8F62) Device Driver & Diagnostics
for RS/6000

If you are interested in the content, I can upload it.

Yes please!, zip or rar them into archives and mail to ryanalswede you know the sign to g mail dot com.

Yes the Linux driver is for the pci I believe. IBM used a bridge chip to go from the same pci amd chip to microchannel which has always been the black mystery box for us.

Thanks a million for your help.

I've uploaded it: https://archive.org/details/pcnet_202211
I can't find a file system on the floppy, but I read them out with dd.
Maybe AIX knows the file system. Do you know which fs they commonly use?
Maybe on my Linux driver a kernel module is missing that supports it.

There were no errors when reading the floppy in my 3.5" floppy drive.

If you want the floppies, I can mail them to you, but you need to pay
for the shipping.

You've probably tried Fast File System (FFS), Unix File System(UFS) or FAT16

I think Journal File System (JFS) was for hard drives.

They maybe in a AIX backup format.

They are.

93H8197.img: AIX backup/restore format file

I'll try to figure out how to mount them in Ubuntu/Debian.

Noticed you used archive.org

What do you make of this response from one else's question? The link doesn't seem to not work.

I can't comment on the legality thereof, but the AIX 4.1.3 source is
available from The Internet Archive:
https://archive.org/download/various_operating_system_source_code

From:
https://comp.unix.aix.narkive.com/qQAjIOdH/aix-source-code

I did download this:
https://archive.org/details/aix-amiga-os-apple-ux-ultrix-dynix-ptx-irix-osf1-solaris-sunos-sysv-sysvr2-sysvr

It has AIX 4.1.3 source code, but the MCA 8f62 didn't come out till AIX 4.1.5. So close!

Could you use the content of my floppies?

I wasn't able to extract the content, but you have the images and you
can use them in AIX.

I will be using your disk images when I get another RS/6000 machine.

That archive site is really neat. Found the IBM AIX 4.1 DDK (device driver development kit) CD iso.
