Supermicro all the way. I've built several 24/7 file servers over the years and all non-server motherboards have lasted around 3-6 years before blowing capacitors, having instability issues, etc. I now have two machines with Supermicro X9SCM + Xeon and they've been rock solid for many years.

Did you try to use this riser in a different system than it came with? No. The riser was from the same system. From the one pic, it also looks to me like there was a bulging capacitor on the motherboard. That may be a trick of how the light is coming off the top of the capacitor. None of the …

I tried this mod. I used 47 pF surface mount capacitors and used capacitance and voltage ratings for the electrolytic caps as described in this thread. I tested the board with a friend who is an Electronics Engineer. With multimeter in hand, we actually de-soldered and re-soldered a few caps …

I'm struggling with this, also. I have two T5720 machines with the PCI riser + expansion cases. I would really like to populate the risers to spec, if possible. I took a look at the PCI Local Bus Specification version 2.2 (That's the version I found through Google.) and in section 4.4.2.1 I found ( …

Replying to myself... I couldn't get the Netgear FA310TX Ethernet card to work. I moved to a 3Com 3C90X card. The 3Com packet driver worked the first time. (Well, except that 3Com's documentation implied that the default software port was in hex when in reality you have to specify hex in the normal …

Thank you so much for this write-up! I have a P3B-F system that I've been monkeying with to try and get a 120G sata drive working with, using a Startech PATA2SATA converter, but it keeps having corrupt data issues. I just ordered a Syba Sil3114 card, and will be trying these steps out once it …

I found this post on Sil3114 when trying to get things working on a P3B-F based machine I've been working on. I'm running DOS 6.22 & Windows 98 (and Debian but that's not a primary use case.) I wanted to throw an old 1TB SATA drive into the machine for use with Windows 98 and had an old Sil3114 card …

From what I've gathered, the Linksys Ether16 is actually a DLink DE-220. Here is a link to the FTP site which has the drivers and setup program to set it to non-PNP mode as well as the user manual. ftp://ftp2.dlink.com/PRODUCTS/DE-220/REVA/ I had no idea.

Do you have the setup disk for the Linksys card? Most ISA network cards I know of can be set to PNP or non-PNP mode via via the setup disk. If your 486 BIOS is non-PNP as you say, your Linksys card will more than likely need to be set to non-PNP mode. The setup disk will more than likely give you …
