3bf216d645 Rewrote the Sound Blaster IRQ system because the old one was designed with a level-triggered IRQ in mind while these are ISA cards with edge-triggered IRQ's. 2021-04-02 08:51:39 +02:00

80095e7a30 Two PIC fixes (implementation of freeze between the two INTA pulses for PC/XT, and find_best_interrupt() treating ISR'd cascaded slave IRQ's the same way as other IRQ's), and removed the incorrect IRQ latch reading. 2021-04-01 05:44:26 +02:00

345a61fa7c Removed the redundant mem_write_null* functions (the few mappings that use them, now use NULL pointers instead) and made the _phys function used by DMA not write to the exec buffer if the address has no write mapping (as in that case, it's clearly not intended to be writable), fixes #1332. 2021-03-30 02:16:01 +02:00

d73011cd4c Early implementation of the Intel 450KX 
450GX & 450KX are the first chipsets intended for the i686 era of processors. Mostly they were used on workstations and servers but also a few general boards. This is an early implementation, not complete due to 86Box limitations in terms of memory handling.

f43284985d Tseng ET4000w32x changes: 
Fixed freezes, once and for all, on win2000 (W32p).
Fixed some graphical glitches under win3.x that were caused by the FIFO (W32p).
Fixed vlb flag, now it loads the VLB rom properly (W32i).
Anything using the ICS ramdacs now has a svga->clock /= 2 in recalctimings (W32p rev c and W32/W32i).

37def45e0e More skew changes, fixed the missing pixels in hdisp in 24bpp mode as well as properly organized hdisp in other bpp modes. 
Clear bit 7 of attr reg 0x10 in the v7 code otherwise it would scramble the colors in 8-bit graphics mode if issued.
