Hi In my experience, to run whdload you will need 2mb chip ram, not impossible in a500 but very expensive. Keep it simple as it is and you will get the best results. My A2000 with kickstart 3.1.4 2mb chip ram, and tf536 has a low compatibility with adf games. Even with modified kickstart, injected …

They are overpriced and overhyped IMO. Sure, they can be downclocked using SetMul which gives them a lot of performance range. However, I would personally just build two separate systems: one for DOS and a second, much more powerful one for Windows 9x gaming. A Pentium 3 or an Athlon system will …

What size eeprom is being used for the XTIDE ROM? You shouldn't need a chip any larger than 16kbyte. I'm not familiar with the Realtek as a XTIDE host, but when using a 3com it definitely needs to have the ROM base address and ROM size set correctly so as not to clash with anything. Hi Sir, I am …

I think the JP3 jumper on your Tseng controls 16-bit operation (vs 8-bit), did you also try the other position? Hi Sir, yes, I have tried, when I move to the other position, I can see squares in character size with various colours on screen in random places and no boot, just freezes. I tried all …

I guess I didn't express myself properly. When I said remove the XT-IDE I meant the ROM or the entire NIC. It doesn't matter what kind of card the ROM is in, that's just a carrier with a bit of address decoding. So again, does it work or hang with the XT-IDE ROM removed (and IDE still connected)? …

Hi guys, in fact I only have an 27c128 with the xt-ide bios burned and placed in an NE2000 compatible card, no xt-ide board. So mkarcher is right. I was probing the B28 pin from ISA connector of the ET4000AX with the near vias/traces around and could not find continuity. Grabbing the oak card I …

This could be an issue with ALE signal and DMA. An old mobo like this wouldn't normally use DMA for HDD but you are using XT-IDE as well. First, does the problem go away if you remove XT-IDE? Second, take a look at the back side of that Tseng, and your other VGA cards. I bet the Tseng has ALE …

With the google code version this method works. The xtide bios is loaded on boot. Using the exact same method with the new version r604 it does nothing. Do I need to use the configuration tool that comes with the r604 version, save the bios with the settings chosen in the program and then burn it? …

How are you flashing the ROMs? With an EEPROM programmer? There is a DOS utility included with the XT-IDE BIOS. Try using that when flashing the BIOS directly on the NIC. Hi! Well, I extract the bios file, open MiniPro Programmer software (free download), I select the chip(27C128) ,open the bios …
