 == Including and excluding optional modules ==
 
-There are few optional modules (most of them are included in official release builds). Reason for modules is simple: it is not possible to get all features to fit in 8k ROM. Official builds are designed so that they include the features most users prefer.
+There are many optional modules (most of them are included in official release builds). Reason for modules is simple: it is not possible to get all features to fit in 8k ROM. Official builds are designed so that they include the features most users prefer.
 
 It is easy to include and exclude modules but it must be done by editing makefile. Makefile specifies how the binaries are build when you execute _mingw32-make_.
 
-Open makefile with Windows Notepad (or [http://notepad-plus-plus.org/ Notepad++]). You will now see all the modules and short description about them. When writing this, the makefile looks like below:

 These are the only parts in the makefile that you need to edit. The defines tell what modules are included in what builds.
 
-DEFINES_COMMON define the modules that are included in all builds.

 DEFINES_XT_LARGE, DEFINES_XTPLUS_LARGE and DEFINES_AT_LARGE are for large builds (15k by default).
 
-Finally there are DEFINES_JRIDE_8K (8k JR-IDE/ISA build) and DEFINES_386_8K (AT build for 386+ with VLB controller support).
-
-If you want to make your own 8k AT build, modify DEFINES_COMMON and DEFINES_AT to include the modules you want. Then rebuild with _mingw32-make all_ or _mingw32-make checksum_.
+Finally there are DEFINES_XT_TINY (XT build with minimal features) and DEFINES_386_8K (AT build for 386+).

 One more thing you might want to change is the size of large build. It is 15k by default (15360 bytes). If you want 16k binary, set ROMSIZE_LARGE to 16384. For 32k build set it to 32768.
 
 
+=== Module information ===
+
+====*MODULE_8BIT_IDE*====
+This module contains support for XTIDE rev 1 and 2 and Lo-tech XT-CF.
+
+====*MODULE_JRIDE* _(requires and automatically includes MODULE_8BIT_IDE)_====
+This module contains support for JR-IDE/ISA.
+
+====*MODULE_ADVANCED_ATA*====
+Adds native support for VLB (and eventually PCI) IDE Controllers. At the moment there is support for QDI Vision QD6500 and QD6580 VLB IDE controllers.
+
+====*MODULE_BOOT_MENU* _(requires and automatically includes MODULE_HOTKEYS)_====
+Adds boot menu to be selected from Hotkeybar. Boot menu displays drive details and allows selecting drive more easily but essentially it has all the same features as MODULE_HOTKEYS.
+
+====*MODULE_IRQ*====
+Adds IRQ support (you also need to enable IRQ with XTIDECFG.COM). IRQs have no real benefit for DOS (but can actually slow transfer rates a bit). You might want to use IRQs with more capable operating systems.
+
+====*MODULE_SERIAL*====
+Virtual hard disks using serial port. [http://code.google.com/p/xtideuniversalbios/wiki/SerialDrives Instructions for emulating Serial Drives with the XTIDE Universal BIOS]
+
+====*MODULE_SERIAL_FLOPPY* _(requires and automatically includes MODULE_SERIAL)_====
+Virtual floppy drives using serial port.
+
+====*MODULE_STRINGS_COMPRESSED*====
+Use compressed strings to save space. This module should be always included.
+
+====*MODULE_FEATURE_SETS*====
+Power Management support (you also need to enable it with XTIDECFG.COM).
+
+
+=== Other features that affect assembly ===
+
+====*ELIMINATE_CGA_SNOW*====
+Prevents CGA snowing at the cost of a few bytes.
+
+====*RELOCATE_INT13H_STACK*====
+Relocates INT 13h stack to top of stolen conventional memory. Has no noticeable performance penalty for AT systems but might slow down XT systems. If you include this to XT builds, make sure that Full Operating Mode is enabled with XTIDECFG.COM. Otherwise stack won't be relocated.
+
+====*RESERVE_DIAGNOSTIC_CYLINDER*====
+Old BIOSes reserve one diagnostic cylinder that is not used for anything. Do not include this if you have use for one extra cylinder. Note that this can cause compatibility problems if you move drives between different systems.
+
+====*USE_186, USE_286 and USE_386*====
+Determines what CPU instructions are allowed. USE_186 limits instructions to those supported by 80188/80186 and NEC V20/V30. USE_286 limits instructions for 286 compatible code and USE_386 limits instructions for 386 compatible code. XTIDE Universal BIOS uses macros that emulate the missing instructions when necessary. Do not use any of the mentioned preprocessor directives if you want to generate 8088/8086 compatible code.
+
+====*USE_AT*====
+Assembles code targeted for AT systems. For example AT builds always operate in full operating mode. Another difference is that AT builds use some BIOS functions that are not available on XT systems.
