Running the CFs in a USB2 card reader on my win10 system on roadkill disk speed, I get: Transcend - max read 15.25MB/sec Indmem - max read 14.50MB/sec Your spreadsheet seems to show that the SD card readers are indeed quite a lot slower than CF if I understand it correctly?

What do people think about CF vs SD for IDE in windows 98 and 2k/xp? I have a CF adapter in my pentium 3 at the moment, but only have 4Gb cards I wanted to get 16gb cards but a 16Gb used CF 133x card is more expensive than a SD-IDE adapter and I have a load of SD cards knocking about that are 16- …

Sure and certain. You can do fast format, but not long format... Long format is useful if you have a protected disc and you forgot the password... With IomegaWare software you can test a cartridge to see if the drive and the cartridge is working . That's because IomegaWare "long format" would be …

250 MB ZIP drive are not fully compatible with 100 MB cartridge. You cannot do a full format. If the disk is protected, you need the Iomega Tools software to access it. Without it Windows XP may not recognize it. If the cartridge works in a ZIP 100 drive and it is not protected, it can be a drive …

The trouble I have is identifying 'good' slockets - most on ebay are of unknown brand and googling the pcb markings for me has always yielded little. Is there a resource for identifying them anywhere? Member Luckybob has made available my compilation of slotket info via this link: https://drive. …

I'm just trying to use 100MB floppy media in Iomega ZIP250ATAPI drive. Under WIndows XP it shows drive in my computer but when I try to open it asks to insert floppy to drive. It doesn't read but floppy is in working condition as I tested it on ZIP100 LPT/USB drives. Question is 100MB should work …

Before blaming the motherboard it may be an idea to try a more reputable slotket than the two that were used up to now. Intel published a list with slotkets that passed and did not pass their voltage requirements testing in 2000 (see attached). The "A" slotket in this thread is a PPGA Celeron …

MSI MS-6119 seems to officially support only 100Mhz FSB. I would first get a system stable at that frequency before going higher. At 112MHz fsb it is stable. Oddly, at 100MHz it isnt. The fun I have with this stuff is just seeing if I can push it. The easiest approach would be to buy a P3 133MHz …

To do list for Slotket B: *check whether G35 and G37 pins are connected, if not, short them. If 1st requirement in the list isn't met, connect these pins to V_1.5 also; *check whether V_CMOS (AB36) is shorted to V_1.5 (AD36) or V_2.5 (Z36) on the slotket, if it's shorted to V_2.5, remove the short …

I wish I had the PNP version though so I could play with the CPU multipliers. I wonder what happens if I install the wrong bios.. I would maybe try it if I had a spare chip and programming tool. The CPUs are multiplier locked. The only difference with the PnP model is you can change the FSB in bios …

Post high ress pictures of bare slotkets from both sides, electric FC-PGA CPU design flaws should be apparent. Images attached, if they arent clear enough let me know and I'll try again. Slocket A has the PGA->FC-PGA wire bodge Slocket B has the voltage pin bodge and I added the capacitors to the …

Slotket A is not fit for the FC-PGA CPU support modification, it's lacks all of the V_CMOS pull up resistors for the CMOS signal group (A20M#, FLUSH#, IGNNE#, INIT#, LINT0/INTR, LINT1/NMI, PREQ#, SLP#, SMI#, STPCLK# etc.) and most likely doesn't even have a trace which connects all of the VTT pins. …

One of the other angles of attack I was looking at was with SoftFSB as this hints (as does that data sheet) that there is a way of setting the PCI clock divider to CPU/4 However, I cant work out the right settings in SoftFSB to do that -- does anyone have any ideas on that?

Oh, I definately am, that's the fun :) Just want to see if there are any avenues to push it to 133MHz -- it's just the challenge I enjoy with these old machines What is the number of the chip in the upper right corner ?

Yes, that's the model of chip just next to the AGP slot on the left. However, the fact that it is still unstable without PCI cards present makes that seem unlikely? And also, I get RAM errors on memory testing - would that fit with an unstable pci bus? One point that remains is that this board was …
