Hello,
First of all you certainly in the right path, the easiest way for you would
be to set up an emulation platform (with emulated hardware as disk image)
and run it on modern hardware.
Emulated disk using disk image will give you flexibility of backup and
emulated hardware will allow simple migration between different HW platforms
getting speed from any new generation.
Not sure if Bochs is the best options for you, other emulators like QEMU and
VirtualBox certainly will provide better performance.
On Corei7 Bochs is able to show ~100-150 MIPS depends on workload (which
might be even better than original PII host was capable, depends on it clock
speed).
For floating point workloads it is worse, for integer it is better.

Subject: [Bochs-developers] Am I on the right path?
Hi Guys,
I am looking to "upgrade" a server without actually upgrading it, but by
redeploying an already deployed system into a Bochs environment.
The existing system is a Sco Unix system running in a PII shell, scsi disks
hanging off an old PCI scsi card, with a 3com 3c905 lan card, and a whopping
768Mb ram.
It has folders in the filesystem with over half a million files which
commands like ls and find are having difficulty processing, which is making
rsync backups impossible.
I need to keep the current system running for about another 6 months, but
also need to up the performance.
I was thinking i could deploy a debian linux system on a Corei7 board, with
8GB ram, pretty much for peanuts, slot in the scsi card and the lan card,
install bochs, and configure bochs to boot directly from the scsi disk, and
get it back on the network.
If I get this config to boot, will I actually have the ability to beef up
the processing capabilities of the bochs machine, and allocate it a decent
chunk of ram?
I have done something very similar to this 10 years ago to salvage a DOS
system for a guy, and it worked quite well, but that was a single user
environment, this is a mutluser environment where performance is going to be
an issue.
Am I set to fail before I start on this path or can Bochs be configured to
exploit the underlying resources to the fullest extent?
Any brief guidance before I start would greatly be appreciated.
Thanks,
Lisa.
