Re: Weird ram problem

It was not until at least 1999 or 2000 when Pentium III came out and 32 MB to 128 MB of RAM became more common and by 2003, 256 MB to 512 MB became more comment also. If you're using the DataExpert OPTi-495SX-based AMI 386 or a ALi-1492-based AMI 486, anything more than 64 MB will not be detected by...

I know. It worked pretty well for a while but the laptop eventually started locking up after logging in.
It would only work if the processor was at least a Pentium Overdrive. :p

I may have misremembered something. I installed Windows Xp on a 486dx2 laptop from cd, but I don't remember if I used a Windows 98 boot disk.
Windows XP is not compatible with processors older than a Pentium processor, because it hard requires CMPXCHG8B and CPUID instructions.

Re: Is it possible to boot a guest from usb?

PCem has no support for USB devices at this time. You can only boot from ATAPI or SCSI CD-ROM or Iomega ZIP drives.

If you want to boot a guest OS from USB, you can place the hard disk image, CD-ROM ISO or Iomega ZIP onto a USB device and boot it from there.

Would it ever be possible to implement this in the future, when the CPU host resources aren't much of a problem, and with an option to select the old (current) behavior?
Not in the next release or in the foreseeable future. You can just forget about the CPU cache. It's a joke.

CPU cache emulation was guesswork in early versions of PCem and since the cache emulation proved to be no improvement to CPU emulation, it was removed.

Please avoid trying to ask for ROMs on this site. Like leilei said, check your sound buffer length and CPU execution percentage as it will start dropping below 100%. On faster emulated processors, the CPU execution percentage will drop requiring a faster PC. On a AMD FX-4300 for example, I will be l...

It sounds like the installer itself is checking for free space and it probably fails over 4GB
That doesn't sound too good. If the hard disk is 4GB or smaller, it will somehow install, correct?

I feel that after a certain point you no longer need to be emulating machines, because basic virtualization will cover those bases for everything but the "it's slow" part. There shouldn't be much in the Pentium 2 age that needs an "accurate" emulator to be able to do everything it needs to do. I di...
