Looks like your machine CMOS setup is password protected. CMOS NVRAM in these machines save settings as you can see in the errors, but security locks are stored in an extra small EEPROM which doesn't get erased across reboots or battery failures. The errors come from CMOS automated routines can't …

I found this also. I do have several 3c905 cards, but these instructions only seem to apply to NT4. Windows 9x does not have these keys in the registry On win98 these values seem to be in "Ndi\params", and where is that?

Just for the record... Combining this technique with MyBCP from Herbert Oppmann (which can uncompress even MAIN module) would make it work for compressed AMIBIOS6 cores, which don't work or get corrupted by AMI BCP7 tools (BCP, MM and OLG logo encoding tools), as long the changes don't mess with the …

No MickySoft Windows NT though. But is that really a bad thing. Actually, there is a technical reason why NTOS never supported ARM until very recently, aside them being underpowered compared with the MIPS, PPCs and Alphas of the era. "Originally it was designed for ARMv5 and ARMv4, but these cores …

It's a bit more complicated than that ol bean. I easily managed to get usb drive formated to fat16 or ntfs4. If you put the NT4 usb sticl with ntfs4 into a win2000 or XP box there would convert then to ntfs 5 (without losing your data) unless NT4 had SP6 applied and could read ntfs5 formatted drive …

Like getting functional usb support on NT4. Something MickySoft insisted was impossible... Still is "impossible" to get in NT4 a full working WDM stack. What you get is some monolitic drivers made by Softex, a filial of Phoenix Technologies, which manage the USB bus in a private way, so only the …

I think Apple kept firewire on life support for a while, for the video professionals market that had it in higher end cameras. It helps a lot it having its own microcontroller to manage all the transfer work by itself instead relying on the host. This also allows to have pretty slim driver stacks …

This is my main gripe with using USB 2.0 cards on a Win9x/DOS rig. They take up too many IRQs and often don't allow you to change their values manually. This nearly always results in a conflict if you're using an ISA sound card. On the other hand, a PCI network card only takes up one IRQ and you …

Since 98SE introduced ACPI, I bet that is a possible problem. You can Google how to disable ACPI in 98SE and see if it helps. Why would ACPI cause a problem? Some motherboards had flawed ACPI implementations that caused strange problems and instability. It has been awhile since I've run into it …

PCI 2.1 vs 2.2. compatibility is basically about whether the card assumes 3.3V to be present and needs it. or not. So it's determined by card design, not chipset. Errr... Yes, and no. MSI style interrupts, while optional in this version of the specification, can make difference in supporting …
