It's completely unecessary to BUMP something that's already on the first page; and hasnt left the front page since the threads conception.

[Robotbeat]

Good point, maybe more people should read it! Here, I'll /\BUMP/\ it for ya!

Hey Dan,<br><br>did you get the SI benchmark prog I sent you?  What scores did ya get?

[Dan East]

I got it, and have tried it, but I need to modify the key mappings. Arrows keys don't work in Pocket Bochs at the moment, and I can't get an actual benchmark without navigating with them. The software seems to run fine under Bochs so far.<br><br>Dan East

[Jack Smythe]

Hi,<br><br>I'm quite interested in the Bochs port for Windows CE, as I have some x86 programs that don't work under PocketDOS.<br><br>However, the Bochs CPU emulation would have to be dramatically optimised if it was going to be of any use on a Pocket PC.<br><br>I've benchmarked the Win32 version of PocketDOS against the Win32 version of Bochs on several Pentium II and Pentium III machines and have found PocketDOS to be 5-15x faster than Bochs. <br><br>I used several benchmark programs I got from Simtel. One of the benchmarks measures MIPS:<br><br>Bochs-1.2.1 = 1.09 MIPS<br>PocketDOS 1.03 (Win32) = 11.57 MIPS<br>PocketDOS 1.03 (WinCE) = 2.74 MIPS<br><br>This was run on a 1Ghz Pentium III (Win32) and a 206Mhz Compaq iPaq (WinCE).<br><br>Jack

I think Bochs runs at 1MIPS by default and that by using this: "ips: 1000000" command in the bochsrc file you can set the emulated IPS. <br>Read more about this in the included bochsrc-sample.txt file.<br>My guess is that by rising the IPS you can get better benchmark results.

[MZGuy]

OLD!

Guess you're going to have to get the arrow keys working sooner or later, but you can get to the benchmark without using the arrow keys.<br><br>Load SI using the switch /DEMO:<br>SI /DEMO<br><br>When it loads, just hit the Next button and it should do the CPU benchmark.

[Jack Smythe]

Hi,<br><br>RTFM! Ok, I've played around with the IPS setting and have found that a value of 4000000 is about right for a 1Ghz PIII machine. However, as Bochs is obviously not synchronising its clock with a real-time clock, any benchmark run under Bochs is going to be meaningless...<br><br>Time to do some real-world tests...<br><br>Jack

[Jack Smythe]

Hi,<br><br>After doing some more testing (with a stopwatch), I've found that the Win32 version of Bochs runs at about 1/3 to 1/2 the speed of the Win32 version of PocketDOS. <br><br>On an iPaq, PocketDOS runs at about the same speed as a 20Mhz 80286 or a 10Mhz 80386. This indicates that Bochs might run at the same speed as a 7-10Mhz 80286 or a 3-5Mhz 80386 on an iPaq...<br>Jack

[Dan East]

Nick, it looks like SI performs some low-level floppy access that the FreeDos BIOS doesn't like. SI exits after it starts up with an "Unknown A: Command" error. After that, the OS is screwed, and the C: drive can't even be accessed. I noticed when I run SI on my laptop with W2k, the floppy grinds for a few seconds when it starts up, even though no disk is in the drive. So, SI must do some funky floppy stuff when it starts up.<br><br>Dan East

[Dan East]

I guess it's about time for another teaser.<br><br><br><br>Unfortunately, the game locks up at this screen. <br><br>Dan East

[Robotbeat]

I can't wait. I want it now. Please? Pretty please?
