Unable to install on Biostar A770 A2+

  • I decided to replace the loud, noisy 1RU linux firewall sitting on my desk at home with pfsense, using an old PC I had sitting in the closet. This system is a Biostar A770 A2+ machine with Athlon 64x2 Dual Core proc and 4 GB RAM (completely overkill, I know, but it's what I have).

    During boot using the 1.2.3 media, I receive an error stating "panic: ohci_add_done: addr 0xcfff1cf0 not found" and then the system reboots.

    I've verified that the BIOS is the latest from the manufacturer.

    I also tried downloading 2.0 RC1 - it installs without issue, but then it doesn't work nice afterwards. I receive a DHCP address from it, but it refuses to display the admin web page.

    If at all possible, I prefer using the "official" release over anything else.

    Any help is appreciated.


  • For what it's worth, I'm able to install OpenBSD 4.9 on this same hardware with no issues.

  • Netgate Administrator

    OHCI is almost certainly USB or firewire related.
    If you aren't using either of those for pfSense I'd try going into the bios and disabling them.


  • Thanks for the reply.

    I'm using a USB keyboard, but I'll see if I can't locate either an old PS/2 keyboard or one of the USB to PS/2 adapters, then disable the onboard USB and report back.
