They were garbage that happened to be 0 in many cases. (real_to_prot()
happens to leave the value of the real-mode %cr0 in %eax and the
memory-size BIOS calls usually don't touch the upper bits of %eax.
The upper 16 bits of %cr0 are usually 0 at boot time, at least on
486's.
Should be in 2.2.
configure() where it always belonged. It was originally slightly
misplaced after configure(). Rev.138 left it completely misplaced
before the DEVFS, DRIVERS and CONFIGURE sysinits by not moving it
together with configure().
Restored the printing of bootinfo.bi_n_bios_used now that it can
be nonzero.
was found, or if there was a checksum mismatch.
This patch should allow the driver to be used with any AMD 53c974
based SCSI card, or with the AMD SCSI+Ethernet Combo Chip found on
some motherboards.
Use the interface MTU instead of the constant when deciding what
packets to accept.
Allow using the SIOCSIFMTU ioctl (e.g. "ifconfig tun0 mtu XXX") to
set the MTU.
These controllers are based on the AMD 53c974, and the driver
does only support those two cards, since it checks for a Tekram
specific configuration EEPROM.
This deficiency (TM) will be fixed soon ... :)

EISA slots to probe. This is mainly intended to allow installing the
system on an HP Netserver with an on-board AIC7xxx EISA SCSI
controller, that is sitting on EISA slot # 11.
Documentation updates explaining this hack will follow shortly.
Note that this can go away again as soon as the EISA device probing
is more intelligent about the address space clash with the PCI address
space.
2.2 candidate.
Not objected by: freebsd-core :)
that we do allow mlock to span unallocated regions (of course, not
mlocking them.) We also allow mlocking of RO regions (which the old
code couldn't.) The restriction there is that once a RO region is
wired (mlocked), it cannot be debugged (or EVER written to.)
Under normal usage, the new mlock code will be a significant improvement
over our old stuff.
Tekram DC390W/U/F, whose config EEPROM can now be dumped, if the kernel
is built with option NCR_TEKRAM_EEPROM.
Other changes:
- add brackets to expansion of OUTB/W/L macro arguments.
- remove unused NCB structure element ns_async
- support sync. SCSI offset of 16 (instead of only 8) on 825A and 875
- correctly identify 53c810A and 53c825A chips
- preserve SCSI BIOS settings of PCI performance options
- remove (already disabled) support for NCR reset because of command timeout
- reverse order of reading of SCSI and DMA specific interrupt cause registers
- add definition of Tekram config EEPROM contents (not currently used)
