/*
* bootsect.S - boot sector for NEC PC-9800 series
*
* Linux/98 project at Kyoto University Microcomputer Club (KMC)
* FUJITA Norimasa, TAKAI Kousuke 1997-1998
* rewritten by TAKAI Kousuke (as86 -> gas), Nov 1999
*
* Based on:
* bootsect.S Copyright (C) 1991, 1992 Linus Torvalds
* modified by Drew Eckhardt
* modified by Bruce Evans (bde)
*
* bootsect.S is loaded at 0x1FC00 or 0x1FE00 by the bios-startup routines,
* and moves itself out of the way to address 0x90000, and jumps there.
*
* It then loads 'setup' directly after itself (0x90200), and the system
* at 0x10000, using BIOS interrupts.
*
* NOTE! currently system is at most (8*65536-4096) bytes long. This should
* be no problem, even in the future. I want to keep it simple. This 508 kB
* kernel size should be enough, especially as this doesn't contain the
* buffer cache as in minix (and especially now that the kernel is
* compressed :-)
*
* The loader has been made as simple as possible, and continuous
* read errors will result in a unbreakable loop. Reboot by hand. It
* loads pretty fast by getting whole tracks at a time whenever possible.

* setup.S Copyright (C) 1991, 1992 Linus Torvalds
*
* setup.s is responsible for getting the system data from the BIOS,
* and putting them into the appropriate places in system memory.
* both setup.s and system has been loaded by the bootblock.
*
* This code asks the bios for memory/disk/other parameters, and
* puts them in a "safe" place: 0x90000-0x901FF, ie where the
* boot-block used to be. It is then up to the protected mode
* system to read them from there before the area is overwritten
* for buffer-blocks.

*
* Fix to work around buggy BIOSes which dont use carry bit correctly
* and/or report extended memory in CX/DX for e801h memory size detection
* call. As a result the kernel got wrong figures. The int15/e801h docs
* from Ralf Brown interrupt list seem to indicate AX/BX should be used
* anyway. So to avoid breaking many machines (presumably there was a reason
* to orginally use CX/DX instead of AX/BX), we do a kludge to see
* if CX/DX have been changed in the e801 call and if so use AX/BX .

*
* This is the low-level hd interrupt support. It traverses the
* request-list, using interrupts to jump between functions. As
* all the functions are called within interrupts, we may not
* sleep. Special care is recommended.
*
* modified by Drew Eckhardt to check nr of hd's from the CMOS.
*
* Thanks to Branko Lankester, lankeste@fwi.uva.nl, who found a bug
* in the early extended-partition checks and added DM partitions
*
* IRQ-unmask, drive-id, multiple-mode, support for ">16 heads",
* and general streamlining by Mark Lord.
*
* Removed 99% of above. Use Mark's ide driver for those options.
* This is now a lightweight ST-506 driver. (Paul Gortmaker)
*
* Modified 1995 Russell King for ARM processor.
*
* Bugfix: max_sectors must be <= 255 or the wheels tend to come
* off in a hurry once you queue things up - Paul G. 02/2001

NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
buffer memory space. NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
the SAPROM, while other supposed NE2000 clones must be detected by their
SA prefix.
Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
mode results in doubled values, which can be detected and compensated for.
The probe is also responsible for initializing the card and filling
in the 'dev' and 'ei_status' structures.
We use the minimum memory size for some ethercard product lines, iff we can't
distinguish models. You can increase the packet buffer size by setting
PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
E1010 starts at 0x100 and ends at 0x2000.
E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")
