I didn't know that TeleDisk couldn't detect weak bits. Unless it's totally different than other systems, it's ridiculously easy to detect. But it's not easy to tell whether bits that change from read attempt to read attempt are supposed to change or whether the disk is just bad. Ok, I'll rephrase a …

Some physical protection checks can work with standard images, namely those that try to verify unusual sectors, because DOSBox reports success for any sector being verified; but it's a small subset of protected games that are so simplistic. TeleDisk format does not support all protection methods, …

Bad news: 1) There is no limiter in the Win98SE himem.sys. 2) Strange, but Win98SE emm386.exe can't initialize UMBs if RAM option was used. Only with NOEMS (59 KB). 3) Statically linked glide games still not work. 4) Blood still can't find my Voodoo2. There is another detector for Blood - the …

Well, have to make a correction. Switched back the TNT2/M64, and had the same error. Lowered the FSB to 50 and the problem went away with both Shadow Warrior and Tomb Raider. So, use the V3 OVL and Tomb Raider will try the V3 but crash (like the compatibility matrix indicated.) Use the V2 OVL and …

If I try to use the Voodoo 2's GLIDE2X.OVL I get a "Failed grSstQueryHardware" message with Shadow Warrior, and a lockup on 3D initialize with Tomb Raider (Blood still refuses to even try.) The Voodoo 3's OVL seems to work fine as far …

Now that the MOD is in place, and everything is working. I pulled the TNT2 and installed a Voodoo 3 3500 TV card. Only now I get a bad video beep code (1 long 2 short.) Before I try to buy another V3, is it a bad card or is it possible this board can't handle the 3500 TV? The problem is, the only …

AFAIR MS-DOS 6.x himem.sys have 64 MB limit so you can use it with any physical RAM size and still have the proper value. Plus there is himemx.sys from Freedos (/max= option). The trouble is - WinME automatically loads himem.sys and you can't change its parameters. Well, I will replace WinMe to …

Well, MOD finished. The MB should be Voodoo 3 & TNT2 safe now. Which is good since I have a TNT2 in it at the moment and have been considering putting a Voodoo 3 in it. I've also maxed everything else out as well. When I get it back together and everything tested out I'll probably proudly post the …

Well, got one of the parts in and made the splice. Now just waiting on the fork connectors (or maybe the proper term is fork spade connectors.) I had to order 50, and they were the smallest I could find. But the cost wasn't too bad. 50 cost me $1.17, while a single connector was $6. Things like that …

I don't know about nGlide, I use OpenGlide. But the screen shots look a lot like mine did until I turned scaling off. In OpenGlide, I had set the INI line "resolution=1.6" since Blood runs at 640x480 and my monitor is a fixed 1366x768 (1024x768.) When I turned scaling off with "resolution=0.0" the …

One final question, non specific to current experimentations. The build is almost complete :) CPU is maxed out. Considering maxing out the RAM (for Windows 98 - 512MB instead of current 386MB.) Maybe put in a DVD I/o a CD-ROM. Maybe replace TNT2 with Voodoo 3 3500. Maybe get a different PSU. Those …

Since my board is currently removed for Voodoo 3 fixing, I've been thinking of switching the jumper on the iP3 from "auto" to "100Mhz" to see if that has an effect. I've also been considering changing it from 1.55V (where it was set when I got it,) to 1.50V (what the CPU is wanting.)

Something curious came up... I had been using a utility someone here gave me (SMB) to alter the FSB speed for some games on the fly. Before, after a reboot, the dip set FSB came back. However, with the iP3 installed it no longer does so. Set the FSB to 50 with SMB, and after a reboot, it's still 50. …

Well, argh!!! Well, went back to the very beginning, and started over with the different BIOS files. Not one of them got to POST (and 2 of them got that far before.) So, I thought maybe I had damaged something when I had removed the CPU to get all the info off of it. When I went to check, turns out …
