It make no difference, because VGA-Register (include extended ) of Cirrus Logic GD542x Familiy is same.

Clockspeeds alone. Otherwise they're the same chip, same design. you said the 5500 is clocked lower? I think you mean to say the 5500 is higher, and the other difference I think is a wider memory bus now that I’m looking more at the issue One source tell, 5500 is lower clocked, most source tell it …

FX5200 and FX5500 use same DIE, (NV34), but FX5500 is clocked less (GPU 230/VRAM 100 instead 250/200 ) Greetings matt

Hello I have picked one old computer from scrap and it is a big suprise: It has Intel Plato motherboard with big memory (32MB ) and SPEA TIGA card. Name of TIGA card is FGA860.4/HE with Cirrus Logic GD5422 VGA-core (not headland on FGA860 from internet ) Harddisc is not dead. I did back up this HDD …

I have check with S3VBE20 on native MS-DOS, not Windows. -> 64MB location is hidden in ROM. Your notice with driver for Windows, it looks good. PCB is arrivied.

Virge PCI driver read over VGA register on Iidex 0x59 & 0x5A ? Modification of ROM for Trio64V+/ViRGE is only Register changing (disable one /two function, but not change of address offset, it was a Trio64V+ PCI ROM ) I am looking after 64M offset in this ROM. But not now. Greetings matt

Trio64V+ and Virge use same pinout. This is interessing point. Trio64V+ and ViRGE is very fast in DOS-mode. No difference, if ROM is same. But i am now on one point: STB Powergraph 64VL is not capable to swapping to ViRGE. Dito my first draw with configable address decoder. S3d-game need linear …

Next success step. ABIT AN4R2 and AN4TR2 doesn't support writeback, becaucse: PCB has a design fail. WB/WT-Pin of 486 is connect to empty solder-joint for jumper. Fail: Jumper short WB/WT Pin to ground. It should connect to VCC, if WB Mode is needed. abitfailWB.png And it run faster :-) Modification …

Yes, this BIOS image is GOOD 😀 I have pile Intel 27512. I pick one and burn image. Yeah, AMD 5x86 run, (detected as (enhanced )AmDX4-S or similar) I can tell: Overclocked Intel DX4 (100@120 ) is a true beast, eaten AMD 5x86-160 in few bench . Thanks Matt

Problem solved ! My multi IO VLB and CF-IDE Adapter is reason for instable DX4-run. Reason: I am lazy and i let run CF-IDE adapter without external 5V supply. (CF IDE adapter run on 5v from IDE Port) Abit board and one vlb ide card doesn't like this way. I plug of 5V supply on CF IDE adapter and DX4 …

Yes, i use SPEA Mercury P64V ROM, which it has high VRAM Clock (66Mhz ) and SPEA Mirage P64 is low clocked. Despite this fact, Trio64 has higher memory bandwitdh. Other benchsession with comprasion between 968VL and Trio64V+ VLB : Same config as above, but 3x 50 Mhz 968VL is also stable by 50 MHz …

Hello No, Trio64V+ VLB run LPB Mode, not Trio64-compatible mode. I have choose this mode, because ViRGE doesn't support Trio64-compatible mode.

I have placed EZ1084CM, adjust. My run with DX-50 stable at 50Mhz FSB. but not with DX4, only 2x Multi. JP9 is bypassing to 5V or for 3.3V over resistor at 5V. I have removed solder jumper. I think: place 3,3V CPU Support at this board is money & time-waste. 😒
