Since when was the original Intel Pentium 64-bit?? I thought Intel introduced 64-bit compatibility with the later Pentium 4 revisions (Cedar Mill core)?

64bit databus width for faster transfers

Page 48: the CPU's top speed is 233mhz (not 200mhz). That's interesting, because on the wikipedia page for Pentiums, the old classic single voltage Pentiums only seem to go up as high as 200mhz. The more modern Pentiums (dual voltage?) CPUs do go as high as 233mhz.

Unfortunately, that doesn't mean the board supports the newer Pentium MMX chips in a direct plug-in-and-go sense. All that means is that it's capable of running a 3.5X multiplier. They probably didn't know at the time the board was made that the non-MMX chips would top out at 200mhz, so they made it support 233mhz for future compatibility.

Also, the manual being published in '98 is probably due to a BIOS update or something that required a revision to the manual. I expect that the board itself made in '96 sometime, or maybe early '97. You're right that November '98 would be quite modern for a P1 board... that would've been the time that the market had largely moved onto Slot1, and the only Socket 7 boards still being made (to my knowledge, anyway) were the AMD-centered Super7 and maybe a few ultra-budget-segment 430TX boards. The move to SDRAM was a big factor there, so the EDO-only 430HX was quite obsolete by that point.

Same with mobo's today...they say it can run DDR2 1300mhz memory but only if you overclock like on my mobo for example

It's a Siemens Nixdorf board, with this code: S26361-D969 written on the PCB. I found the spec for it here -

Hello from Germany,
I received a S26361-d969-b11 in the last few days.
My mainboard is equipped with a Pentium 166Mhz MMX, the cache expansion module and 2 MB graphics memory.
As soon as a bios battery is installed it works perfectly, without it the CMOS gets confused because the socket seems to short-circuit the contacts.

Unfortunately, the mainboard only supports hard disks up to ~8500MB, so I went looking for a bios update and unfortunately found that support in Germany has apparently been discontinued, the website no longer works. the support website linked here in the article also no longer seems to provide drivers.

does anyone still have drivers to download and possibly even a bios file?
