Subject: IBM/4.3 Fix to 6152 ethernet patch V1.12
Index: sys/ca_atr/if_un.c
Description: This patch fixes a problem with the new Ungermann-Bass
ethernet driver derived from patch V1.12. The problem was
that vmunix would hang during autoconfig with two ethernet
adapters present. This simple patch (V1.14) supports two
adapters. It disables interrupting the adapter
during autoconfig.
Fix: Apply patch V1.12 to the December 88 source code, if you
have not already done so. Then apply this patch V1.14 to
the already patched code.
