If you have FreeBSD installed and have the kernel source, then you'll
find the low-level device driver for the Adaptec aic7xxx controllers in
the following files:

  /usr/src/sys/dev/aic7xxx/*
  /usr/src/sys/pci/aic7870.c
  /usr/src/sys/i386/eisa/aic7770.c
  /usr/src/sys/i386/scsi/93cx6.[hc]
  /usr/src/sys/i386/scsi/aic7xxx.[hc]

The mid-level scsi code is found in:

  /usr/src/sys/scsi/*

You can also find them at ftp.cdrom.com in
/pub/FreeBSD/FreeBSD-current/src/sys/...
