Re: 430VX and Win98/ME now crashes PCem

Seems the Red Hat problem has led to all sorts of issues. I hope it's exposed proper bugs rather than just been a pain!

Re: Floppy emulation on old versions of Linux

I investigated this a little more. The same lockup problem occurs in Red Hat 5.2, but this is available as a bootable ISO CD. It wasn't anything to do with booting from the floppy itself. If I disabled the floppy controller in the BIOS the CD would boot normally (but obviously without any floppy dri...

Re: Amstrad 1512 HD Version

The XTIDE BIOS is already in PCem I think, you can select the controller under "HDD" in settings. The Xebec BIOS must be called ibm_xebec_62x0822_1985.bin and copied to the roms folder.

Re: Amstrad 1512 HD Version

Ok, you need the BIOS for the Xebec adapter for it to work. You should be able to find it online.

Alternatively you might be able to get XTIDE to work, this is emulating a modern bit of hardware for old 8bit XT PCs and its BIOS is included.

Re: Amstrad 1512 HD Version

You select the MFM fixed disk adapter as the hard drive type in settings, it's the original IBM XT hard drive controller and emulation is provided by PCem.

Re: Amstrad 1512 HD Version

You can add the MFM fixed adapter and use one of the supported disk types (type 13 at 20mb is fine), and it will automatically work under DOS 2 or later. It installs its own BIOS to enable support, and DOS 2 is required for HD support.

Re: Floppy emulation on old versions of Linux

The image works on VirtualBox and on the unofficial PCem fork - maybe there's some bug with how it sends raw codes to the drive instead of using the BIOS?

Floppy emulation on old versions of Linux

With older Linux systems that were installed using a floppy there seems to be a bug with floppy drive detection. The boot begins but when the kernel finds the drive(s) it freezes. I've tried a few emulated machines and it's the same result. Here is Red Hat Linux 4.1's boot floppy: https://ufile.io/p...

Re: Linux

Distributions from around 2000 or so should run fine on a 486, I remember it was popular to stick Linux on those back then. The desktop systems were usable for sure if a bit rough around the edges.

You probably have EMM386 running with NOEMS (or not running at all). Use the RAM option to enable EMS and VCPI.

Yeah, just one port with master/slave rather than two ports with two sets, as was common for all machines from the pentium onwards until SATA replaced IDE.

Re: CDROM on older machines

Ah, I thought PCEM must be injecting something since as you say the BIOS on those machines can't see anything. First, I'm not sure what you call "older machines" all PCem machines are more than 20 years old... By default, PCem assigns D: to the CDROM... but that can be easily configured in the menu ...

CDROM on older machines

I see that PCEM by default wants to add a CDROM drive to E: and that on newer machines that will add it to the 2nd native IDE controller (master). But what does it do on older machines with just one controller? Does it add its own BIOS like an expansion card? I've noticed the CD drive is still detec...

Re: v13.1 released!

With this release I get an SDL2.dll not found error at start up, doesn't happen with 13.0.

edit: I know I can fix it by downloading the DLL (which works), just not sure if this extra requirement in 13.1 is intentional.

The XT (original PC) line had 8 bit expansion slots, the AT (286 lines) had 16bit, which are backwardly compatible with 8bit. 386SX systems also had 16bit because everybody still used 16bit expansion cards when the CPU was released.

Re: Best option for Windows 3.11 and high res/colours

That driver doesn't run at all (I guess it's for NT). But the 2nd one I downloaded last night was definitely for Trio64 and not Trio64V and it was limited in the same way.

Re: Best option for Windows 3.11 and high res/colours

That's the same as the one I had. I found another one dated earlier, and it was the same limitation. I'm not sure there are any 3.1 drivers that support the higher colours/res.

Re: Best option for Windows 3.11 and high res/colours

I downloaded the only Trio64 drivers I could find, version 1.70.04. The highest it will do is 64k colours at 1024x768 - anything higher than that res is limited to 256 colours.
