Re: Using special machine types

Between machines with similar features and performance, the difference will mostly be related to nostalgia and preservation. Sometimes there are bugs or quirks (real or from the emulation) that will make software work in one but not in another.

Re: Hard disk not recognized in win 98

With some motherboards in PCem I have to set the CHS translation setting manually, even though in the real hardware "Auto" was enough. Try this.

Re: Are ISO+OGG (or similar) CD-ROM images supported?

CD-audio also has very basic error correction (most data tracks use more of the sector for extra error correction/detection). When I found out that a RIP that had no errors in it had a different hash when ripped in another drive, I went on to re-rip my entire collection with another drive to double ...

Re: CPU ID:NEC V20 instead of Intel 8088 on PCEM / 86box

Quick note: the recently added Xi8088 BIOS knows how to differentiate between new/old 8088s and NEC V20 and works fine with PCem (detects as old 8088)

Re: [Patch] Packard Bell Legend 300SX

Thanks for the tip, leilei! I've been using ImgBurn for regular CDs and Alcohol 52% for titles with copy protection. In this case, however, there was no difference when using different software. I'm going to set up a 32-bit environment to see if this alse happens with the 32-bit recompiler.

Re: [Patch] Packard Bell Legend 300SX

It's an obscure 1995 magazine CD from my country. I've been dumping everything in my possession lately. The ISO is 134MB bzipped but just running the .exe file without any data is enough to trigger the crash. I believe there would be no problem in distributing this specific executable for you to test.

-Turbo selection works (fix also applied to the Toshiba t3100/t1000) - Sarah, this is very intrusive to the cpu subsystem and I don't know much about it, please review carefully

Re: [Patch] Packard Bell Legend 300SX

I start the machine it post but when it goes to boot it crashes. It seems to happen when certain cdrom images are mounted at boot. I can confirm that this happened to me some time ago with the install CD of a linux distro, mounted at POST = crash in various AMI bioses for Pentium. Forgot the report.

The Xi8088 is a great project by Sergey Kiselev to build a XT-clone, I've built it myself along with the other boards by Sergey and they work great. The system is a XT along with some AT and PS2 features like PS/2 mouse, AT RTC/NVR, two PICs, etc. More info in http://www.malinov.com/Home/sergeys-pro...

I've seen it happen in real hardware, but not with the AWE32. Wrong and/or missing music and even sounds in Duke3D under Windows. Generally a reboot would fix it.
