- * 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.

- * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.
- * <stiker@northlink.com>
- *
- * Fix to work around buggy BIOSes which don't 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 .

- * (troyer@saifr00.cfsat.Honeywell.COM) 03Oct92
- *
- * some changes and additional features by Christoph Niemann,
- * March 1993/June 1994 (Christoph.Niemann@linux.org)
- *
- * add APM BIOS checking by Stephen Rothwell, May 1994

- * High load stuff, initrd support and position independency

- * <mj@k332.feld.cvut.cz>
- *
- * Extended memory detection scheme retwiddled by orc@pell.chi.il.us (david
- * parsons) to avoid loadlin confusion, July 1997
- *
- * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.
- * <stiker@northlink.com>
- *
- * Fix to work around buggy BIOSes which don't 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 .
- * Michael Miller, April 2001 <michaelm@mjmm.org>
- *
- * Added long mode checking and SSE force. March 2003, Andi Kleen.
