e97a7a15c6 Declared `unittab' as static. It was bogusly shared between the asc and 
gsc drivers.

0af805cb7d Use PCB_SAVEFPU_SIZE instead of a too-small size in savectx(). This 
bug only affected FPU emulators.  It might have caused bogus FPU states
in core dumps and in the child pcb after a fork.  Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.

Cleaned up #includes.

Clarified GUS DMA Settings.
Other misc. changes.

This should hold us over until I can finish cleaning up TASD, and finish
reintegrating all of the FreeBSD changes to the sound driver.  At that time
this document will be removed, and it's information moved to the handbook.

6b740ac6e9 Add a lock for DMA Channels to prevent two devices from using the same DMA 
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed

eac7371c68 Allow specifying the BIOS drive number. Removed the hd drive type. 
hd essentially wired the FreeBSD drive number to 0 without changing
the BIOS drive number.  Now the numbers can be specified independently.

Replaced the BOOT_HD compile time flag with with BOOT_HD_BIAS.  Defining
the new flag as 1 should give the same behaviour as defining the old
flag as anything.  I haven't tested defining these flags.

e20b650550 Work around a braindead signal handling in many newer HP printers. 
They don't have BUSY de-asserted by the time they ACK (and thus cause
an interrupt).  The workaround is to try seeing if the BUSY will be
de-asserted soon, and if not, to use an incremental backoff and
semi-polled mode instead of the fixed timeout with 1/2 s we've been
using previously (that caused the printer to run really slooow).

Printers that have been working previously should not be affected by
this.
