Limited to 66MHz FSB? Wouldn't it be possible to mod/hack the PLL to get 100MHz after all? If not, a Mendocino@533MHz would beat the hell out of a Katmai running at 400MHz@66MHz FSB. Clock-for-clock Mendocino averages at about the same performance as Katmai, with small differences depending on …

Most PCI 2.2 cards are backwards-compatible with PCI 2.1, but some are not. The RTL8139C is NOT compatible with PCI 2.1 buses. So if the PCI WiFi NICs work in the same systems that the RTL8139C works in, and the RTL8139C fails in the same ones, it's probably the PCI compatibility issue.

Could it be a PCI revision thing? ALi's Aladdin V has a PCI 2.1 bus, possibly the NICs need PCI 2.2. Easy way to check: this behaviour is known for the Realtek RTL8139C (note the C!) Ethernet chip. That happens to be - by a wide margin - the commonest PCI NIC around. See if one of them shows the …

Difference can be high/low density modules (some laptops only require low density). One or both of the modules may be bad. One or both of the slots in the laptop may be bad. Terms like "high density" and "low density" are meaningless outside of a very specific context in time. If you want to help, …

"Disk controller failure" can be as simple as incorrect CHS settings (due to loss of CMOS data) or a dead/dying HDD. What happens if you attach the same drive with the same settings to a different system?

This was already answered - 8b digital audio needs an 8b IRQ, so <=7 What about DOOM ? It crashes on 1, 5 and even 7. As i said it only works when i go to irq=10 and then run "dsdma" legacy emulation. Is there a conflict? No, that's as designed: the PCI card itself resides at IRQ10, then uses the …

Oh God! You really don't understand or you mock... You can set any resources combination but if you go with AWE card you'll not get 8 bit digital sounds in PoP and in some other old games. No, we're just going offtopic. It's clear enough about the 8b digital audio bit, didn't think that was even a …

IRQ 5 was used for HDD controller on XTs, so was not available to sound, which is why really early SB games default to IRQ 7.

Compaq and odd pinouts? Where the connector was remotely standard, they always seemed to be normal enough (unlike Dell at in the same period...). But if you have a continuity tester, it's easy enough to find GND, +5V (power LED) and +12V (fan headers) on the board and compare that to the power pins. …
