The 2100+ is a 13x multiplier over 133 (DDR266) FSB (real clock speed 1733) 1500+ is 10x multiplier, real clock speed 1333 - so if the FSB is mis set to 100, 13x 100 is a real clock of 1300.... close enough to be miscounted as a 1500+ Some boards set the FSB in BIOS, others in links, some let you …

S3 Savage 4 PCI is a desirable card? - ooh, I've got one of those somewhere, not sure if it's still in an old system - some nostalgia as it was my first ever card beyond 2D Windows accelerators.

For switchmode power supplies, they would also have to be low esr, though in some cases, going far lower in esr than originally designed for may also upset the circuit - I believe someone tried converting a PSU to polymers, but a big part of the problem with that may have been having to make do with …

A GeForce 4 MX440 is really a kind of Geforce 2 in disguise. S3 Savage 4 was the first accelerated GPU I ever had, handy for a few things that use the MeTaL API.

The separate Panasonic / Sony / Mitsumi interfaces died out with 4x drives, if I recall... connecting an IDE drive to an old style interface may damage one or both. If the CDROM has options of master/slave it is definitely IDE. You may have problems with older IDE hard drives which predate …

A variation to the "same or higher" voltage, sometimes you can go lower if you know the circuit voltage. In motherboards, you will have the stock 12V (typically 16V caps), 5V (6.3V caps, could possibly see 10V ones), the 3.3V on ATX or 3.3V regulator for AGP. The main place where you may often be …

I think you need 8k x8 (32k will do) in the other sockets for tag, only one might be needed for writethrough, but the dirty bit for writeback wouldn't fit in just one (unless using less than half the max RAM)

I'm guessing that will be VIA audio, so it will be the 220b version for VT82C868B from http://download.viatech.com/en/support/driversSelect.jsp But also the (rather large) VIAFMTSR (can't remember where you get that, as it's not included in the driver set

One crazy idea, try waitstating the SCSI BIOS... http://download.adaptec.com/pdfs/user_guides/aha1540b_um.pdf Also, instead of the smartdrv double buffer, maybe try ASPI4DOS.SYS /W - not sure if that only works on 386 systems though, or if it's applicable to 286 If the /W doesn't help (uses extended …

I'm wondering, if the SCSI BIOS is only operating in a single 8 bit ROM, then it may be an issue with the "fast decode" which uses a 128k block for 8/16 bit selection. Is there an option in BIOS that will shadow the SCSI BIOS range so it does not have to access the ROM across the ISA bus. This would …

For >33 JP2 waitstates the bus (memory?), as well the likely need to use JP12 to waitstate VLB. Cachechk will probably show the L1 as faster, the L2 and RAM as slower.

Had a 7IXE4 (the Socket A version). Fussy about RAM, needs low density - 128MB generally work fine, 256MB modules are a problem, as the high density seem to be more common
