the Pentium 200 could arrive to the games of 1999 even without a 3D card? Considering that it doesn't handle 3D well it could be useless right? for 1999, pretty much. i mean, see for yourself how ut99 (beta) runs on 233mmx: https://www.youtube.com/watch?v=sJTgMUqxqQ0 older stuff like quake 2 and …

you could run some tool like speedsys or chkcpu and see what they detect as CPU speed. it's pretty typical that FSB doesn't run at the exact specified number, but a fraction under/over that, though 4 mhz difference on CPU clock seems more than usual indeed. what does the board report when it's set …

Keep in mind Windows 95 panics after 350mhz out of the box. Yes there's patches about it but they're quite difficult to apply in the day. i always thought the 350 mhz issue was specific to AMD K6. this however suggests there was a similar issue with 333 mhz pentium iis that was fixed (?) in some …

there's a major misunderstanding here, the colors on these startech headers are completely arbitrary and it's always mandatory to check each invidiual one. on mine it's red GND, brown data, yellow VCC and green clock, but many other variations have been posted here: https://www.vogons.org/viewtopic. …

on certain socket 7 mainboards, there is a jumper for setting CPU CLK pin voltage to either 5V or 3.3V, and that jumper is on 5V by default. now, according to the datasheet, that pin is indeed 5V tolerant on pentiums up to P54CS, so it shouldn't be an issue. however, what is the point of this jumper …

yes, my 2.0a ms serial mouse had that slight laggyness to it even on a pentium 3. playing with the com port settings in windows didn't change anything either. to test the differences of ps/2 vs serial, one could change between those two interfaces on a mouse that supports both.

ball mice have an additional mechanical element to them, so i'd say they are inherently laggier than optical mice. if you are used to the latter, with USB and high polling rates on modern PCs, then i could see how one would make such observations... granted, the microsoft mice seem to be among the …

If shadowing is not an option for whatever reason, the same performance gain can be achieved by loading the ASPIxDOS.SYS driver only. ASPIDISK.SYS is only required if you have more than 2 HDDs or have the SCSI BIOS disabled. interesting, i typically load aspi8dos.sys with the 2940 series anyway for …
