19871cbb96 We probably ought not to call INT13 with interrupts disabled. 2007-07-10 04:32:30 +01:00

b90d321dfb Change %dl fixup rules for INT13:
INT 13,08 : read number of drives from 40:75
INT 13,15 : do nothing
all others : restore original value of %dl

8bce52d348 Set CF by default, clear on success (rather than clearing and setting
on failure).

4ff85d9f15 Add -mpreferred-stack-boundary=2 to i386 CFLAGS as it's almost always a win. 2007-07-09 03:32:54 +01:00

4c418d2100 Use net_device_operations structure and netdev_nullify() to allow for
safe dropping of the netdev ref by the driver while other refs still
exist.

Add netdev_irq() method.  Net device open()/close() methods should no
longer enable or disable IRQs.

Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.

fbda4837b0 Allocate heap at first usage, rather than assuming we can fit it in
below _text.  This should help with the gPXE-on-gPXE-via-PXE case.

e42eba4af4 Use a common base-memory packet buffer for DHCP construction (as used
by PXE and NBI) and UNDI packets (as used by undinet and UNDI).

5f17089b14 pxe_netdev now holds a reference to the network device.
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.

Add PXENV_UNDI_SET_STATION_ADDRESS.
