For the 1 or 2 people still running this server, or have one serving as a doorstop due to a dead network card I though I'd share a solution I stumbled across.
Aspire easyStore H340
Marvell Yukon 88E8071 PCI-E Gigabit
Current OS Ubuntu 18.04 Server
Several years ago I began getting intermittent network connectivity issues with my Marvell Yukon Gigabit LAN connection, and resolved that issue by purchasing a USB 100MB LAN adapter. A year or two later I begin getting failures at boot with HD lights 1 and 2 lit, and over time the boot failures were almost constant. The H340 Service Manual on manualslib indicates this is a LAN Controller issue.
I ordered the diagnostic video adapter (after all these years running with a headless machine!) "VGA Adapter for Acer Aspire H340" for about $30 on eBay. After plugging it in, per the Service Manual I looked for a suitable jumper for JP3 to enable Diagnostic mode, and not finding one I used the one from JP1 (BIOS Recovery Jumper). So now I have JP1 unjumpered and JP3 jumpered. The VGA Adapter cable works flawlessly and I could watch the POST on a connected monitor, and to my surprise the server booted normally! I tested several reboots and coldstarts and the boot error has not recurred; I closed the box up with the short VGA Adapter cable tucked inside and have left the jumpers in this position for now.
The only effect I have noted is that the Yukon LAN Controller no longer appears on my hardware list but the USB LAN 100MB adapter is providing a tolerable network solution.
Cheers,
John
