Count me in ! How much will be unpopulated PCB alone ? I need something that won't generate vertical stripes on LCD (in 320x200) - my Trident TVGA9000c unfortunately does this.
Re: GLX Player the only XT player ? Check Mod Master...
Posted on 2020-08-27, 06:16
That's great news ! I'm looking forward to the new release ! What is the feature you are looking for ? VGM support. Although SBVGM works on my 286, the usage isn't very handy (therefore I assigned vgm and vgz extensions to SBVGM in Norton Commader). I will wait as long as it is needed for proper XM …

I'm almost sure that 2.8GHz/400CPU will work, but don't bother with Celeron. Even slower P4 CPU will be faster than 128kB Northwood Celeron. They are probably worst Intel CPU.

Re: Help with flashing a S3 Virge GX PCI card BIOS
Posted on 2020-07-15, 20:29
I'm afraid that this card isn't prepared to flash its bios on board :( None of the Virge cards I have seen were. Fortunately chip itself could be re-programmed. You have to remove EEPROM chip from card and program it in external programmer. By the way - BIOS version 2.01.07 may be better choice …
Re: 386sx25 on vlsi 311 Mainboard overclockable to 33MHz?

You can also try to program FLASH/EEPROM using ethernet card with Flashrom program.
Re: 386sx25 on vlsi 311 Mainboard overclockable to 33MHz?
Posted on 2020-07-15, 08:17
Yes. Eproms starting with 27 are UV-erasable (28xxx are EEproms and 29 are Flash devices). But classic eproms usually needs higher programming voltage 12V-21V, so you have to use dedicated programmer. Some time ago very popular (among hobbyists ) was Willem Programmer (which was connected to LPT …

Unfortunately programmer you linked is for serial eeproms, so not suitable :( Your eprom is parallel one. If you remove sticker from IC, you will get eprom type (probably UV erasable 64KB device - 27512 or 27c512). Any 64kB pin compatible eeprom or flash will be ok. For example SST27SF512. Probably …

Anyone care to recommend me some cool demo's for my 286-20,1MB, VGA, Sound blaster ver 2.0? I'm not sure about memory requirements, because I have 4MB in my 286 PC, but those demos below are I think quite good. Wish by Majic12: https://www.pouet.net/prod.php?which=2074 Realtime 1.2 by Impact …

Get DX4 which can be jumpered to 3x and 2x multiplier and you will have 2in1 😀
Re: Going from 3gb to 120gb - how to setup Sectors? Cylinders? in BIOS.
Posted on 2020-06-22, 10:15
That a 40GB drive works is encouraging, that means your BIOS is more recent than I expected . I think that Windows just bypasses BIOS and probes drive by itself. Few times I connected drive to IDE channel which was configured as 'none' in BIOS and Windows discovered it anyway . So I think it is …

I'd rather try AT29C512 because it is mentioned in rtflash documentation. It also can be bought very cheap from ebay.

You need 64k B chip not 64k b . Organization should be 64kx8bit = 512kb. I'd search for something like 28512 (eeprom) or 29512 (flash) You can try flashing using network card and uniflash. http://web.archive.org/web/20120228193303/http://www.rainbow-software.org/download/uf140.zip Changelog mentions …

I had SE440BX-2 in the past and remember that this board have YMF740 not YMF724. Maybe 3rd version also have this cut-down chip ? Try it's dedicated drivers: ftp://ftp.spez.com.ua/driver/mb/intel/se440bx2/index.html
