+.Dt BONITO 4 loongson
+.Os
+.Sh NAME
+.Nm bonito
+.Nd Memory and PCI or PCI-X controller
+.Sh SYNOPSIS
+.Cd "bonito0 at mainbus0"
+.Cd "pci0 at bonito?"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports both the Algorithmics Bonito64 memory and PCI controller
+on Loongson 2E-based systems, or the onboard memory and PCI-X controller
+found on Loongson 2F-based systems, which is a very close design, albeit
+not compatible with the original Bonito.
+.Pp
+Differences between the two models of controllers are hidden at the
+.Nm
+driver level.
+.Pp
+The
+.Nm
+driver also handles PCI interrupt routing; on systems featuring a
+.Xr glxpcib 4
+PCI-ISA bridge to which legacy devices are connected, it will also
+handle legacy interrupts.
