I didn't realise there was a 32 GB Scandisk limitation. It can only scan up to 32 GB of data? Which version of Scandisk? I don't think I have any 5400 RPM drives left in any of my systems. All IDE are 7200 rpm and SCSI 10k rpm, with perhaps one or two at 15k rpm. I used a few 5k rpm drives in the …

I plan on making a clone disc of my IBM 5x86c-133 system, which also uses the Promise Ultra100, and runs Win95c and WinNT4.0. It's much faster to get all my software up and running through this means. Both OSes support 80 GB drives. I might try benching the FX's onboard DMA mode-2 IDE controller …

The Asus PCI/I-P54TP4 430FX board has been selected for the socket 5 build. I ran into a snag yesturday as the 2x multiplier jumper only works for P54 chips and not model 1&2 AMD K5 chips. I had to add a BF1 jumper to the motherboard to fix this problem. Made a new post on that mod here: https:// …

As part of my effort to get a socket 5 working with an AMD K5-PR200, https://www.vogons.org/viewtopic.php?f=46&t=70561 , I discovered that the 2x jumper of an Asus PCI/I-P54TP4 430FX board won't set an AMD K5 to 1.75 or 2.0x. The 2x jumper on this board is for CPU's which only have the BF signal. If …

The 128GB IDE BIOS fix for the FX board allows me to properly detect and use an 80 GB UltraATA drive on the motherboard's IDE controller. The online literature suggest that it supports IDE bus mastering, so I am guess this is pre-Ultra DMA, so would it be DMA mode2 at 16.6 MB/s? And would the …

The wires are the same colour and go to the same location on the header, but on one of the cables, the wires are …

Nice concise summary of results there. It was interesting to see how the POD100 was only 3% faster than the AMD X5-160 in DOOM, but 55% faster in Quake. So all 486 chips work with SCSI VLB when the WB jumper is set? Or you didn't have to set the WB jumper on the SCSI card for the system to work …

Well, it is not just the mouse - the keyboard power goes though this fuse as well. The keyboard and mouse are connected to a KVM, which draws power from the Keyboard connector. Those are the main items. I'm not sure if any other motherboard component is connected to this fuse. But my guess is that …

Yeah, thought it seemed like a lot too, but when I went digging through my pile of dead motherboards to find fuses, I saw one with an 8a. I haven't run into one of these 1995-1997 era Asus boards with a different PS/2 mouse pinout, but I guess I'll measure it out to be sure. I only have so many …

I've moved onto the FX board now. These 1995-1997 Asus boards usually use the same pinout for the PS/2 mouse header, but for some reason, when I plug my mouse into the ps/2 mouse cable, the 125V/3A fuse near the keyboard connector opens. I replaced the fuse and it blew again. Any idea what this is …

Another update, the 430NX board won't work properly with the Cyrix 6x86 and AMD K5 when L2 cache is enabled. Works fine when L2 cache is disabled though. Looks like I'm down to one board, the 430FX, pending any any issues during preliminary testing. Something else interesting is that the NX board is …

Well, the ECS SiS 500 and Asus SiS 500 board are out of the running now. While the ECS board would POST fine with the K5, I couldn't get the board to boot from a floppy. It would stall during floppy boot up. Its probably some CMOS setting that's not happy because the same thing happened with a …

Yes, the Proserva is HX. Odd to use a socket 5 in there. It would be interested to see if some of the systems have "socket 5" and some have "socket 7" written on the ZIF. I searched for "EDO" and "extended data" in the SiS 500 series manual and the search returned nothing. Manual was dated: January …
