v1.4b - Fix freeze on early K6-2 steppings

Small issue with the WHCR layout on K6-2, it changed mid-model, so after stepping 8.

Also EFER register settings are not available on old K6-2, causing a freeze.

v1.4 - K6 / K6-2 pre-CXT support

As stated, this release adds support for some basic functionality for AMD K6 and K6-2 pre-CXT CPUs.

K6 can only do L1 cache control and Write Allocate, while K6-2 can also do Write Ordering and Data Prefetch control.

Also, the misleading help text asking you to type "/help" for usage info is fixed :P

K6INIT_D.EXE is a debug version with verbose output for debugging problems.

v1.3b

Bugfix release to fix crashes enabling L1 when it is disabled in the BIOS.

v1.3a

Bugfix release to fix /skippci and /skiplfb (Fixes #3)

v1.3

• Add chipset tweaks for several (using /chipset parameter) ALi and SiS chipsets
• Change order of LFB and PCI frame buffer scans to increase the likelyhood of accelerating actual FB-using software, especially on DOS.

v1.2

• Write Allocate no longer fails when the 15MB hole is specified
• Reworked behavior of /auto with other parameters, it is now seamless
• Introduced new skip parameters that help change /auto's behaviors
• Running in V86 mode no longer crashes (fixes #2) but gives a helpful message
• added /quiet parameter for reduced print output
• PCI / LFB scan warns instead of errors when the MTRR list is full (i.e. too many locations found)

V1.1: Data Prefetch, Multiplier fixes, etc.

What's new?

• Changed parameter usage help parameter to /?
• Fixed Set Multiplier not working at all
• Fixed unsupported Multiplier settings not being rejected
• Fixed Multiplier 6.5x not being rejected
• Set Multiplier now gets blocked on non-PLUS CPUs
• Added feature to enable/disable Data Prefetch
• Program now detects Windows and refuses to run on it
• Improved error handling for PCI/AGP BAR scanning
• Added feature to list all PCI/AGP BARs

v1.07: Fixes and Windows detection

Fixes:

• The program now prevents itself from operating under Windows
• Fixed a crash with certain systems when detecting PCI BARs

v1.06 - add support for PCI/AGP frame buffers (EXPERIMENTAL)

K6INIT now scans both VESA LFB modes and PCI/AGP graphics card BARs, bringing a potential speedup in especially Windows applications.

v1.04a - Complete rewrite, adds L1/L2 cache control

What's new?

• Complete rewrite
• Nice fancy new on screen appearance
• Better error feedback
• Finer MTRR control introduced, regions can now be specified distinctly as write-combined and/or uncacheable
• Better memory detection, adding the int 0x15, ax=0xe820 method
  • Fixes support for FIC VA-503(A) motherboards
• Fix write allocate region being a few KB too small
• Add control for L1 and on-die L2 cache (if present)
