d393e61d8a Temporary hack to work around the "TX overflow" problem in the interim 
period before updating to the new driver API (which can cope with
having TX packets in progress).

52de4935f9 Add 4 bytes to maximum frame length to allow for the frame checksum. 
(This actually matters once you try using TCP, because you *will*
receive full-sized frames.)

bcdcd796fb 32kB window is actually larger than our typical receive ring size. 
Shrink to 4kB for now.  We might want to see if it can be made
genuinely indicative of the RX ring size in the new TCP
implementation.

3b51c719d3 Generalise three-wire interface to generic SPI interface. 
Update rtl8139 driver to instantiate an SPI interface with a three-wire
device attached.

ab4f96e525 Move per-transition delays from generic bit-bashing layer to i2c layer 
(since SPI bit-bashing will require different delay semantics).

df4b503a8c Added null trap code for debugging. (Must be included by adding 
--nulltrap to the make target at the moment.)

476d02051f Windows Server 2003 sulks if we feed it an empty region in base memory 
as a result of our memory map editing, so strip out any empty regions.

17eea9f933 Fix bug with >256 cylinders. 
Allow our functions to return a non-zero, non-error status (since the
INT 13 Extensions Check has to return the API version in the register
that is otherwise always used for the error code).

Report a non-zero API version from the INT 13 Extensions Check; GRUB
now uses extended reads.

ad1aca0634 - separated curses.c out into separate source files to optimise 
library use later on
- some small mods to existing functions

fdf62528ca It's astonishing how long really fundamental bugs can survive without 
being noticed...

763b7e2ef9 We now have just romprefix, rather than having isaprefix and pciprefix 2006-06-06 15:41:21 +00:00

ef37f78cbe Cut out almost all the optional code paths, drastically simplifying the 
flow of control through this code.

We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.

UNDI loader is still missing.

286bf68faf Added a very quick and dirty compatibility layer, to allow 
not-yet-updated drivers to at least function.

1f394c2f7c Backing out last change; no immediate plans to make the whole block-device 
layer asynchronous, so keeping the sync/async boundary within aoedev.c
seems cleanest for now.

d6866202f9 Until we have a functioning UDP stack and PXE API again, there's not much 
point trying to use the old boot sequence.  Replaced with a call to the
AoE demo code, so that people can at least build and try something useful.

d21fc3610f Added sample AoE test code to tree 2006-06-01 11:05:36 +00:00

f6d20bb0f4 Put in a method to get the MAC address for the AoE target. (It's not 
elegant, but it works).

99ef98d0bf ATA devices are now asynchronous. The ATA layer itself now performs the 
async_wait(), though we may wish to move this higher up the stack, and
consider making the block device model asynchronous.  (There is only a
marginal cost for synchronous devices, since they can simply call
async_done() before returning; async_wait() will work seamlessly in this
situation).

cf96d325d8 Missing from previous checkin. 
This is the core portion of the async I/O interface.
