This adds preliminary emulation of the first-gen Samuel core, used in the VIA Cyrix III CPU, at clock speeds from 66 to 700 MHz. This also moves the 440BX emulation out of the dev-branch.
Things working:
- CPUID
- Windows 98SE
- Timings seem identical between WinChip/W2's integer section and this
Things left to do:
- 3DNow on old dynarec
- Half-speed FPU (currently simulated with WinChip 1 timings instead of WinChip 2)
Added the Toshiba Equium 5200D. A CU430HX board. Presents the same issues as the TC430HX.
The unknown Headland board names received their respective PCem-like clone names (Phoenix 286 clone, Quadtel 286 clone).
- Delinked CPU bus speed from PCI speed
- Changed the CPU multiplier from an integer to a double
- Changed the CPU cache/mem cycles on the K6-2s from fractions to integers
- Fixed cache/mem cycles on the faster Cyrix MIIs
- Fixed some spacing issues that I created
- Added IBM 486SLC2/40 because somehow I didn't know it existed
- Revoked Dynarec support on the IBM 486 CPUs after several PS/2 machines were buggy with it
- Disallowed Pentium OverDrive and 3.3V 486 CPUs on the AMI 486 clone, Award 486 clone, IBM PS/1 2133, and IBM PS/2 model 70 Type 4 due to discovery that they used either Socket 1 or the original 486 socket
- Disallowed split-rail voltage CPUs (P55C, 6x86L/6x86MX, K6) on all Socket 7 FX and some HX motherboards that don't support it
- Fixed a lot of wrong multipliers on 5th-generation CPUs
- Added mem and cache cycles for the faster K6-2s/K6-3s above 300 MHz
Headland IQS seems to be troublesome with the Headland chipset emulation of 86Box thus it was removed. The G2 12HS on the other hand replaces the "Unknown Quadtel Headland".
Added a few 286 boards:
- Unknown Phoenix Headland
- Unknown Quadtel Headland
- Headland IQS(Phoenix A286)
- The AMI, Quadtel and Phoenix variants of IBM AT
- Samsung Deskmaster 286
- A Dev branched Micronics 386 Board
