This patch applies experimental implementation for ATI Korean VGA which is ATI-28800 compliant and supports KSC-5601 Korean character set specification.
If you need BIOS ROM and font ROM image for it, please send PM to me.

Edit : This patch has been incorporated here.

Current version of ATI-28800 on PCem fails to show BIOS mode 0x54(800x600 16color), 0x55(1024x768 16color), 0x63(800x600 256color), 0x6A(same as mode 0x54). And recently I've got OTI-067 VGA BIOS version 1.06 and when I use it in PCem, machine is running in monochrome mode and changing screen mode t...

This patch does the following. Reworked against version 13.1. - Implemented IDT limit too small exception on real mode. - Changed AT compatible machine's reset vector to F000:FFF0 instead of FFFF:0000 - Set IDT limit to 0xFFFF on 286 and 0x03FF on 386+ when system reset as real machine does. - Chang...

Did you select correct Hard Disk C: Type on BIOS Setup? You should set type 32 or type 47 with Cyl=1024, Head=15, WPCom=65535, LZone=1024, Sect=17 on BIOS Setup like below screenshots.

- DMA wait control state register is now writable.

Hello. I don't know if this post is closed. I recently discovered tath the Vtech Laser XT/3 has an 8086 Cpu not an 8088 like the Vtech Laser Turbo XT. If i recall correctly. the EMS memory chips can be installed in 256kb incrementens in the 8088 system (example 256/512/768/1024 kb) and 512 kb in th...

This patch changes right window key to ctrl+alt key combination on non-windows enviroment. It makes easy to enter CTRL+ALT+DEL and CTRL+ALT+ESC combinations on Linux(On Linux, it is difficult to enter the CTRL+ALT+ESC combination. Some BIOS like Award286 clone uses it to enter CMOS setup).

Check the output of: $ pkg-config --variable pc_path pkg-config Per example, here (on Arch Linux) gives: /usr/lib/pkgconfig:/usr/share/pkgconfig One file called sdl2.pc must exist into one of those directories. I did what you asked me to do, but nothing like the screenshot below. pkg-config-result....

It seems that you have installed SDL2 into /usr/local . Uninstall it and then re-install it with: $ ./configure --prefix=/usr Rationale: Configure script installs packages into /usr/local/ by default (i.e. if prefix is not set). As pkg-config * will search for .pc files in the directories /usr/lib/...

It looks like you have not installed the SDL2 libraries. Rationale: There is a bug into sdl2.m4 file since version 2.0.5. It causes that the configure script does not exit when it does not find the SDL2 libraries. The configure script fails when checking OpenAL because it tries to compile a test li...

Unlike legacy Allegro version, the wxWidgets version fails to find OpenAL library during configuration on CentOS 6.x. All required library is installed.

This screenshot is legacy Allegro version. This screenshot is wxWidgets version.

The first is From Toshiba and the Second from GW-286CT GEAR using the SCAT chip emulation developed by Gratpsycho. In the Toshiba there is no Mappeable memory. This mappeable memory is the ´large page frame', this memory is backfilled and managed by the EMS 4.0 chipset. Not all chipsets support lar...

I found a bug that MS-DOS version 5.0 or greater version crashes when kernel is loaded in HMA area when I use 1024KB memory configuration. To fix this problem, you should add mem_mapping_set_exec() call to t3100e_map_ram function in t3100e.c. Previous code: /* Bit 4 set if upper RAM is mapped to hig...

This patch ensures that STAT_IFULL to be set immediately after sending keyboard self-test command applies only to the Toshiba T3100e. This solves the problem that Samsung SPC-4200P/SPC-4216P does not boot. And it also apples all even command value between 0xF0 and 0xFE to reset CPU. This solves the ...

Out of curiosity, I saw in the commit that the Samsung SPC-4216P can use a file called phoenix.bin as well as (instead of?) the split roms. What was that file for, exactly? Sorry if this seems like a trivial question. The phoenix.bin was dumped by MS-DOS DEBUG and splited ROM files was independentl...

This patch fixes typo and removes io_sethandler that was used when debugging.

* The Samsung SPC-4200P and 4216P both of the them have a problem when testing the XMS memory after configuring the EMS memory in the BIOS, they detect the remaining XMS wrong or directly as 0kb of XMS avaiable. (also the 4200p only support 2MB of RAM and 4216p supports up to 5MB. 5MB is enought fo...

Is this something which is actually causing problems? IIRC readmem*/writemem* are already catering for the problematic misalignment cases. I have not yet experienced a problem in almost all usual cases. However, I have written this patch because I think there may be a problem in a few unusual cases...

This patch improves accuracy when word/dword/qword memory accessing at addresses across page or segment boundaries.

This patch fixes Internal IDE related trouble in non-windows enviroment.

I'm having trouble with the Samsung and KMX systems - the Samsung just hangs before initialising the video card, the KMX just beeps. Any suggestions? The KMX-C-02 BIOS that can be downloaded by Internet search is broken. Please let me know your e-mail address via PM and I will send you a correct BI...

This patch adds three machines mentioned below that previously posted before but not applied. Reworked against rev 872.

- GW-286CT GEAR(286)
- Samsung SPC-4216P(286)
- KMX-C-02 (386sx)

This patch applies all even command value between 0xF0 and 0xFE to reset CPU. XENIX uses command value 0xF0 to reset CPU.

Edit : This patch has been incorporated here.

¡Hello! Sorry if it is a bit off topic. But is possible to add EMS support to NEAT machines?. The emulated AMI BIOS 286 and DTK-386 SX clone, both, have a NEAT chipset. I know they uses a different EMS driver, but i don't how different are NEAT and SCAT chipset for instance. ¡Thanks! According to t...

I've just modified model name as you pointed out and re-uploaded patch file.

This patch adds KMX C 02 machine using 386sx CPU and Chips&Technologies 82C836(SCATsx) chipset that is successor of 82C235. Experimental 82C836 chipset emulation is also implemented in this patch and two more machines that uses 82C235 chipset is also included in this patch that is submitted but ...
