* 93/06/28 bde
* Initialize top bits of %eax for setting _ouraddr. start.s
* initialized them suitably, but this isn't documented, and the BIOS
* isn't documented to preserve them.
*
* Use addr32 for setting _ouraddr. Without this, there were extra bytes
* 0, 0 after the store. These decode as "add %al, (%bx,%si)" in 16-bit

Fixes from bde, including support for loading @ any MB boundary (e.g. a
kernel linked for 0xfe100000 will load at the 1MB mark) and read-ahead
buffering to speed booting from floppies. Also works with aha174x
controllers in enhanced mode.
*
* 93/07/06 bde
* Restored BOOTSEG to 0x9000 for distribution. It should be decided
* at boot time to locate the bootstrap immediately underneath the
* debugger or whatever is in high memory. This isn't safe yet,
* because it might make the read-ahead buffer might lie across a 64K
* DMA boundary.
*
* 93/07/03 bde
* Some floppy BIOS's can only handle reads of one track, so a LOADSZ
* of 16 doesn't work. 15 will do for now.
*
* 93/06/29 bde
* LOADSZ is 16, not 14. The BIOS can handle a minimum of one floppy
* cylinder so it can always handle 16 sectors starting at head 0,
* sector 1.
*
* 93/06/28 bde
* Changed addr16's to addr32's. One before a useless "xor %ecx, %ecx"
* did nothing (removed both prefix and xor).
*
* Initialize head = %dh = 0 for floppy case.
*
* Fixed #ifdef DEBUG ... #endif that split data32; jmp load. If
* DEBUG is defined then the jmp doesn't get prefixed. This is fatal
* iff the jmp is long. Usually the jmp will be short and the prefix
* unnecessary. But it is more likely to be necessary if DEBUG is
* defined.
*
* 93/06/27 bde
* Removed bogus Int 21. There is no Int 21 BIOS call. The drive
* number is passed to here in %dl and the Int 21 is at best a nop.
* Some BIOS's treat Int 21 as a stray hardware interrupt and shut
* down all in-service interrupts. This should not be a problem
* because this are not an interrupt handler so there are no
* in-service interrupts, but ...
*
* Fixed fd/hd decision. "%dl ge 0x80" (signed comparison) was always
* true, so fd's were treated as hd's. This was not a problem because
* the boot block has a partition table.
*
* Reduced BOOTSEG and added breakpoint so that debugger can look at
* this. Having a fixed boot address is bad because some machines don't
* have 640K and others have debuggers and/or BIOS stuff in high memory.
*
* 93/04/30 bde
* Commented out "<leading white space> # %". It's not C, and gcc-2's
* cpp doesn't allow it. "# identifier" isn't C either but works for now.
*
* Use $ EXT instead of $EXT to avoid broken DOLLARS_IN_IDENTIFIERS stuff
* in gcc-2.3.3. (Bug is still in gcc-2.4.5 but is avoided by using .S
* files.)
*
Revision 1.1 1993/03/21 18:08:42 cgd
after 0.2.2 "stable" patches applied
* Revision 2.2 92/04/04 11:36:29 rpd
* Fix Intel Copyright as per B. Davies authorization.
* [92/04/03 rvb]
* Need to zero dh on hd path; at least for an adaptec card.
* [92/01/14 rvb]
*
* From 2.5 boot:
* Flush digit printing.
* Fuse floppy and hd boot by using Int 21 to tell
* boot type (slightly dubious since Int 21 is DOS
* not BIOS)
* [92/03/30 mg32]
*
* Revision 2.2 91/04/02 14:42:04 mbj
* Fix the BIG boot bug. We had missed a necessary data
* before a xor that was clearing a register used later
* as an index register.
* [91/03/01 rvb]
* Remember floppy type for swapgeneric
* Add Intel copyright

Revision 1.2 1993/07/11 12:02:22 andrew
Fixes from bde, including support for loading @ any MB boundary (e.g. a
kernel linked for 0xfe100000 will load at the 1MB mark) and read-ahead
buffering to speed booting from floppies. Also works with aha174x
controllers in enhanced mode.
*
* 93/07/06 bde
* Delete LOADMSG define (not used).
*
* 93/06/29 bde
* Use EXT.
*
* Initialize GDT and IDT pointers at boot time.
*
* Convert (drive | head | junk) to drive arg for boot() (not strictly
* necessary - boot() only uses drive & 0x80).
*
* 93/06/28 bde
* Initialize top bits of %eax for setting _ouraddr. start.s
* initialized them suitably, but this isn't documented, and the BIOS
* isn't documented to preserve them.
*
* Use addr32 for setting _ouraddr. Without this, there were extra bytes
* 0, 0 after the store. These decode as "add %al, (%bx,%si)" in 16-bit
* mode would clobber something (except %al is very likely to be 0 :-).
*
* Clear the bss. This may be unnecessary. Some is already cleared in
* the disk image.
*
* Loop if boot() returns.

Fixes from bde, including support for loading @ any MB boundary (e.g. a
kernel linked for 0xfe100000 will load at the 1MB mark) and read-ahead
buffering to speed booting from floppies. Also works with aha174x
controllers in enhanced mode.
*
* 93/07/06 bde
* Restored BOOTSEG to 0x9000 for distribution. It should be decided
* at boot time to locate the bootstrap immediately underneath the
* debugger or whatever is in high memory. This isn't safe yet,
* because it might make the read-ahead buffer might lie across a 64K
* DMA boundary.
*
* 93/07/03 bde
* Some floppy BIOS's can only handle reads of one track, so a LOADSZ
* of 16 doesn't work. 15 will do for now.
*
* 93/06/29 bde
* LOADSZ is 16, not 14. The BIOS can handle a minimum of one floppy
* cylinder so it can always handle 16 sectors starting at head 0,
* sector 1.
*
* 93/06/28 bde
* Changed addr16's to addr32's. One before a useless "xor %ecx, %ecx"
* did nothing (removed both prefix and xor).
*
* Initialize head = %dh = 0 for floppy case.
*
* Fixed #ifdef DEBUG ... #endif that split data32; jmp load. If
* DEBUG is defined then the jmp doesn't get prefixed. This is fatal
* iff the jmp is long. Usually the jmp will be short and the prefix
* unnecessary. But it is more likely to be necessary if DEBUG is
* defined.
*
* 93/06/27 bde
* Removed bogus Int 21. There is no Int 21 BIOS call. The drive
* number is passed to here in %dl and the Int 21 is at best a nop.
* Some BIOS's treat Int 21 as a stray hardware interrupt and shut
* down all in-service interrupts. This should not be a problem
* because this are not an interrupt handler so there are no
* in-service interrupts, but ...
*
* Fixed fd/hd decision. "%dl ge 0x80" (signed comparison) was always
* true, so fd's were treated as hd's. This was not a problem because
* the boot block has a partition table.
*
* Reduced BOOTSEG and added breakpoint so that debugger can look at
* this. Having a fixed boot address is bad because some machines don't
* have 640K and others have debuggers and/or BIOS stuff in high memory.
*
* 93/04/30 bde
* Commented out "<leading white space> # %". It's not C, and gcc-2's
* cpp doesn't allow it. "# identifier" isn't C either but works for now.
*
* Use $ EXT instead of $EXT to avoid broken DOLLARS_IN_IDENTIFIERS stuff
* in gcc-2.3.3. (Bug is still in gcc-2.4.5 but is avoided by using .S
* files.)
*
Revision 1.1 1993/03/21 18:08:42 cgd
after 0.2.2 "stable" patches applied
* Revision 2.2 92/04/04 11:36:29 rpd
* Fix Intel Copyright as per B. Davies authorization.
* [92/04/03 rvb]
* Need to zero dh on hd path; at least for an adaptec card.
* [92/01/14 rvb]
*
* From 2.5 boot:
* Flush digit printing.
* Fuse floppy and hd boot by using Int 21 to tell
* boot type (slightly dubious since Int 21 is DOS
* not BIOS)
* [92/03/30 mg32]
*
* Revision 2.2 91/04/02 14:42:04 mbj
* Fix the BIG boot bug. We had missed a necessary data
* before a xor that was clearing a register used later
* as an index register.
* [91/03/01 rvb]
* Remember floppy type for swapgeneric
* Add Intel copyright
* [90/02/09 rvb]
