source: xtideuniversalbios/trunk/XTIDE_Universal_BIOS/makefile

Last change on this file was 625, checked in by Krister Nordvall, 22 months ago

Changes:

  • Added a configuration option to let the BIOS store RamVars to an UMB when Full operating mode is enabled. This is primarily for XT class machines with RAM in the UMA (which apparently is a common thing these days).
  • Added two new builds specifically for IBM PS/2 machines. This is for support of the new McIDE adapter from the guys at zzxio.com. Note that the additional hardware specific code (under the USE_PS2 define) is for the PS/2 machines themselves and not for the McIDE adapters, so any controller in an IBM PS/2 machine can be used with the USE_PS2 define.
  • Moved pColorTheme out of the range of ROMVARS being copied over when doing "Load old settings from EEPROM" in XTIDECFG. This fixed a serious bug from r592 where loading a BIOS from file and then loading the old settings from ROM would corrupt 7 bytes of code somewhere in the loaded BIOS.
  • Optimizations (speed and size) to the library. Browsing the menus in XTIDECFG should now feel a little less sluggish.
  • Hopefully fixed a problem with the PostCommitHook script where it sometimes wouldn't find the CommitInProgress file. I say hopefully because testing this is a nightmare.

2# Makefile to build XTIDE Universal BIOS. #
3# #
4# Valid makefile targets are: #
5# all Removes existing files and builds binary files in \Build (without checksums) #
6# small Builds only binaries smaller than or equal to 8 kiB (without checksums) #
7# large Builds only binaries larger than 8 kiB (without checksums) #
8# custom Builds custom binary without checksum (change DEFINES_CUSTOM / BIOS_SIZE_CUSTOM first) #
9# clean Removes all files from \Build #
10# checksum* Same as 'all' but also applies checksums to the binaries #
11# strings* Compress src\Strings.asm to src\StringsCompressed.asm #
12# unused* Checks if there are any unused functions that can be removed to save space #
13# #
14# * at the end of target name means that Perl is required for the job. #
15# Build directory must be created manually if it does not exist. #
16# #
17# #
18# Following modules can be included or excluded: #
19# MODULE_8BIT_IDE Support for 8-BIT IDE cards like XTIDE #
20# MODULE_8BIT_IDE_ADVANCED Support for memory mapped and DMA based cards like JRIDE and XTCF #
21# MODULE_ADVANCED_ATA Native support for some VLB IDE controllers (requires USE_386) #
22# MODULE_COMPATIBLE_TABLES Support for ill behaving software that tries to access DPT directly #
23# MODULE_BOOT_MENU Boot Menu for selection of drive to boot from #
24# MODULE_EBIOS Enhanced functions for accessing drives over 8.4 GB #
25# MODULE_HOTKEYS Hotkey Bar to boot from any drive #
26# MODULE_IRQ IDE IRQ support #
27# MODULE_SERIAL Virtual hard disks using serial port #
28# MODULE_SERIAL_FLOPPY Virtual floppy drives using serial port (requires MODULE_SERIAL) #
29# MODULE_STRINGS_COMPRESSED Use compressed strings to save space #
30# MODULE_VERY_LATE_INIT Initialize on INT 13h if our INT 19h handler is not called #
31# MODULE_POWER_MANAGEMENT Power Management support #
32# MODULE_WIN9X_CMOS_HACK Hack for Windows 9x compatibility #
33# MODULE_MFM_COMPATIBILITY Restores BDA drive count for MFM/SCSI controllers that expect to be #
34# the only hard drive controller in the system #
35# #
36# Not modules but these affect the assembly: #
37# ELIMINATE_CGA_SNOW Prevents CGA snowing at the cost of a few bytes #
38# RELOCATE_INT13H_STACK ** Relocates INT 13h stack to beginning of stolen conventional memory #
39# NO_ATAID_VALIDATION *** Excludes code that tries to ensure proper communication with drives #
40# NO_ATAID_CORRECTION Excludes code that corrects illegal CHS values from some CF cards #
41# USE_086 Applies WORD alignment padding for use with 8086/V30 CPUs only #
42# USE_186 Use instructions supported by 80188/80186 and V20/V30 and later #
43# USE_286 Use instructions supported by 286 and later (defines USE_UNDOC_INTEL)#
44# USE_386 Use instructions supported by 386 and later (defines USE_286) #
45# USE_AT Use features supported on AT and later systems (not available on XT) #
46# USE_PS2 For use with IBM PS/2 machines only (defines USE_AT) #
47# USE_UNDOC_INTEL Optimizations for Intel CPUs - do NOT use on NEC V20/V30/Sony CPUs #
48# USE_NEC_V Optimizations for use with NEC V20/V30 CPUs only #
49# CLD_NEEDED Only needed for compatibility with buggy software/BIOSes #
50# EXTRA_LOOP_UNROLLING_SMALL Improves transfer speed on some CPU + IDE controller combinations #
51# EXTRA_LOOP_UNROLLING_LARGE Same as above but faster and uses more ROM space #
52# #
53# ** AT Builds only (when USE_AT is defined) #
54# *** Use this only when certain known good drives are not being detected (eg WD Caviars) #
