What's new in VBEMP NT?

AVALIABLE ONLY VIA PAID SUPPORT BY REQUEST. PAYPAL, REVOLUT, SKRILL OR CRYPTO.

1. * * * (released in 2019)
   • Match and use static table VESA modes with fixed refresh rate.
   • Scan ROM to detect and match BIOS PCIR to PCI ID.
   • Acquire ISA/PCI/AGP/PCIe access ranges so no other device can use it.
   • Interlaced modes support (60i/50i, PAL/SECAM/NTSC) for direct connect VGA to TV using VGA-SCART cable
   • Rewritten DDC monitor detection and EDID parse, now it is more accurate
   • Custom control for margins size (up to 4% of overscan)
   • Show vendor and device ID in videoadapter properties.
   • VSYNC, HSYNC polarity now has default values according to VESA standard
   • Installation: For Windows NT 3.5x install is more safe, since 8-bit modes are set first
   • Installation: Fixed bug with AMD-ATI videoadapters install with dual devices
   • Automatic LFB position detection for some ISA/VLB cards (Cirrus Logic, S3, Trident)
   • Filter disabled VESA modes, which are present, but non-functional
   • Support for non-VESA VGA-only cards - now it correctly drops to 320x200x256
   • Refined lfb address detection
   • Fixed memory leak when enumerating a lot of modes
   • Updated Cirrus Logic/QEMU driver with all above changes and partial CL-GD546x support
   • In debug version: vbemp.log created & rewritten each system start
   • In debug version: detect PCI-X, Hypertransport, PCI-E
   • Updated IEGDNT driver - it can add new VESA modes (mosty widescreen) to your Intel integrated video
   • Updated Control Panel Applet VBEMP.CPL: On-the-fly display calibration support
2. * * * (released in 2024)
   • Added new driver for ALPHA and MIPS Windows NT architectures
   • Access ranges count lowered from 10 to 6.
   • Detect LFB and AR prefetch from PCI config space.
   • Show VGA/nonVGA, DAC size in videoadapter properties.
   • Test framebuffer RAM before mapping it.
   • Support for generic IBM VGA compatible (no VESA BIOS)
   • Detect chip ID for Cirrus.
   • Updated Control Panel Applet VBEMP.CPL: Multi-monitor/-adapter support.
3. * * * (released in 2025)
   • Initial non-banked 4-bit support (NT3/NT4).
   • 128k buffer available for 4-bit.
   • New vendor support ARK Logic (EDD8), SIS (1039), Avance Logic (1142), C&T (102C).
   • Updated vendor support Trident (1023).
   • Fixed scan ROM looping, partial match.
   • Initial overscan color support.
   • Detect and use LFB size.
   • Modified internal refresh filtering.
   • 320x200, 640x200, 640x350, 640x480 4-bit support added.
   • Set palette registers for 4-bit.
   • Non-linear fallback in set mode.
   • Debug dump CRT registers.
   • Added new static modes for VGA-SCART and 832x624 (Mac).
   • Full ModeX support 320x/360x on x240,x400,x480 in Windows 2000 and later
   • Detect ISA/VLB device ID, bus type for Cirrus.
   • CIRRUS: Stable linear support for ISA/VLB.
   • CIRRUS: Refresh rate limits changed.
   • Updated Control Panel Applet VBEMP.CPL: ANSI/Unicode and Windows 9x/ME support.
