Package opening time :) Interesting packaging [/attachment] Second motherboard, Supermicro P3TDE6. Dual socket 370 with Tualatin support. IMG_3671s.jpg Both motherboards have AGP Pro and both 3.3V and 5V PCI-X slots. I need to get some chassis, beefy ATX PSUs and some more ECC REG sdram. :cool: …

Just so you know, SB no longer means "Sound Blaster". It has been appropriated by the Chinese, and now it stands for "sha bi", which roughly translates to "dumb cunt". Seriously, whenever I see a brick wall or an elevator, some clever grade school student has carved an "SB" into the surface. You …

Did some more research based on my guess of J35, J36 and J37 that are close to the frequencygenerator. Came up with this. 2155.jpg So it seems that J37 switches between 25 and 33MHz bus. Yes ! Now it’s working at 100mhz. I removed jumper 37 and set the other CPU jumpers to work with Overdive CPU. …

Yes, In the CDMKE driver package readme.txt file it reads that /SBP:220 is optional and not needed so I did not add it originally. But It appears it was needed, Also unlike IDE driver you don’t assign the drive letter with /L:D This CDMKE.SYS driver automatically assigns the drive letter.

Yes, it works with games and music. I use these settings to get CDROM to work. I also had to install the Sound Blaster 16 drivers. Autoexec.bat MSCDEX.EXE /S /D:MSCD01 /V /M:15 Config.sys DEVICE=CDMKE.SYS /D:MSCD01 /SBP:220

Yeah, My first CDROM drive was a 2x Sony with the SONY IDE controller. So I want to see if I can get this to work.

Okay, I am just using this connected to the sound card. Single drive. Will it work with a regular straight threw single IDE cable ? Again: that drive uses the Panasonic interface, not IDE. It will neither work when connected to IDE, nor with an IDE CD-ROM driver. You need a sound card with a …

It's not IDE but using the Panasonic interface. You can use up to four of these on one cable, that's what the jumpers are for (ID 0 to 3). It won't ever work when connected to IDE, you may even damage the hardware doing this. Okay, I am just using this connected to the sound card. Single drive. …

Hi, I have an Sound Blaster 16 CT1740 card with an IDE interface. I think this was a Sound Blaster kit with Sound card and CDROM. The CDROM is a Sound Blaster proprietary with jumper that read 0123 ( No master or slave or cable select ) It is NOT SCSI , It is a 40-pin IDE drive. Not sure what speed. …

The motherboard in that PS/1 probably only has a 25MHz FSB. It's called a PS/1 or PS/Valuepoint for a reason :evil: The multiplier setting should be 3x. Other than that leave everything stock. Well, Supposably it supports a 486dx-33 So I don’t know why I can’t get it to work with this overdrive CPU …

Does the DX4 Overdrive run at 100MHz? When this pc was designed, that CPU was not released yet. By the way; upgrading the RAM to 64MB is useless unless you are going to use Windows 95 with a memory hungry database or CAD program :wink: I can only get this CPU to run at 75mhz. Is that going to be …
