dbj ef5d25c147 use bios' idea of the basemem size and create the kernel stack
at the top of it instead of hard coding 0x90000

mycroft 6816b631ab Nit: Make bootrealseg conforming. 1999-11-07 01:06:37 +00:00
drochner db5d01fc72 back out the "ep"/"ex" guessing part of the previous - the check was
removed from the kernel and the device name is only informational now
1999-11-05 22:57:39 +00:00
mycroft 3c702c1d8d Recognize the 3c595, and use `ex' for 3c90x now. 1999-11-03 12:38:54 +00:00
mycroft dfc00b5b24 Back out the GDT changes in the previous. Didn't mean to commit that. 1999-11-03 09:55:32 +00:00
mycroft 1ee8f66dfe Picking a few nits...
* The direction flag wasn't set right in the presence of ROMDEBUG.
* There were missing data32's.
* We weren't as careful as we should be with relocations.

kleink 5663256d0a Unlike in an i386 a.out assembler, where in an .align n directive n is meant
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.

Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.

drochner 29a8d333b6 put biosdiskclose() inside LIBSA_NO_FS_CLOSE 1999-08-03 19:46:22 +00:00

drochner 19e64942a2 don't printf(NULL), not even in the DEBUG case
(It doesn't hurt the bootloader, but the junk output hangs my serial
console.)

drochner 998ac16bb7 add some casts for gcc -Wall, from David Rankin
<drankin@bohemians.lexington.ky.us> per PR port-i386/7554

fvdl 4fbaa0b272 Restrict "out of CHS range" check to harddisks. 1999-05-04 17:14:55 +00:00
fvdl ec559f688b Be more careful with saving registers around the "out of CHS range" check. 1999-05-02 12:44:34 +00:00
christos 57e4b98787 - Use the proper multiply instructions so that we don't get truncated. 1999-04-30 15:31:17 +00:00
fvdl 48003b2c88 Only use int13 extensions if the sectors can not be read through the
older CHS interface. This works around stupid BIOSs who report that
int13 extensions are present and functional, but fail when you actually
use them. Like Adaptec SCSI BIOSs.

christos c5ec77e01b use new loadfile 1999-04-28 09:14:22 +00:00
drochner ca053f4364 remove an "unmodified" so that the copyright notice will hopefully match
pk's "BSD-style (clauses: 2; no acknowledgements)" pattern
1999-04-22 10:27:16 +00:00
drochner 982c55e22c another nit in error handling: don't try to print out a NULL filename
(which means "use default" and is dealt with properly by open())
1999-04-17 11:18:36 +00:00

drochner 7d5e1f9211 fix error handling: almost all errors were ignored 1999-04-09 20:12:57 +00:00
drochner 552f55e726 Call bi_getbiosgeom() after loadfile() returned successfully. This avoids
a memory leak if loadfile() gets an error.

drochner 5d86b86370 #ifdef out the last change for the branch 1999-04-01 19:36:09 +00:00
drochner 3497f157fd On serious boot errors, dont lock the machine. Instead, wait 3 seconds
and call the ROM BASIC vector. This might behave differently on different
machines, but normally it allows to reboot without power-cycling.

fvdl fb1b0e7a0b Shifting ecx without explicit prefix in real mode won't work. 1999-03-30 22:35:21 +00:00
drochner 17de7b2576 adapt to set_geometry change: we don't have to correct the geometry
anymore
1999-03-30 17:58:05 +00:00
drochner 62031ff978 fix some disk handling problems introduced in the last commits:
-read retries were botched, use the right sector count
-read-ahead buffer was effectively unused
-concentrate the handling of the weird BIOS geometry report at one place
-fallback for old floppies left cylinder count uninitialized
1999-03-30 17:55:48 +00:00
drochner 4feae58ec1 sync to changed geometry handling in the standalone code 1999-03-30 11:51:35 +00:00
fvdl b815df141c Only use the total number of sectors information field from the EDD if
the bit is set that declares the geometry valid. The spec itself says
that this field isn't covered by the "geometry valid" bit, but at
least one BIOS implements it that way.

sommerfe df8e0043e3 Fix compile warning in getcomaddr() 1999-03-12 04:14:37 +00:00
fvdl 8371eb7a88 Clean up the BIOS disk matching code a bit (better naming, one structure
and sysctl to export to userland). Also, only use total number of sectors
given in the extended parameters if the physical chs geometry is
marked invalid. Hopefully fixes a problem where BIOSs would not correctly
fill in this field.

fvdl bc38bb1052 Declare nhd to be unsigned char, as we're only copying one byte to it.
From Matthias Drochner.

drochner b477d700f2 add support for 3c905b TX 1999-03-10 10:37:38 +00:00
fvdl bdb770bc34 Create a list of native disks too, and make it retrievable. It contains
all matching BIOS disks per entry, so that we have complete match info.
Enable the matching code.

drochner 743494ae88 add a function to pass the "memory map" ie the outcome of INT15/0xe820,
to the kernel
