Nice, I wondered if there was any native Pentium M board with a slot for a real video card. And it has the mobile version of the chipset too.

Looked at the SMART data on some HDDs. My laptop has a 40GB Hitachi with 7,987 power ups, 13,968 start/stops, 15,315 hours running time, and 487,509 load/unloads. The funny thing is a 500GB WD-green that I just got two years ago has roughly double those numbers! No wonder it was cheap...

GeForce FX series should work fine in Win98. What version of DirectX is installed? Did you run dxdiag and see the spinning cube, etc. ?

When it restarts does the Windows boot menu come up, and if so what options are displayed? Or maybe you need to mess with BOOT.INI

What about hacking the boot sector to change the year in the CMOS before loading the OS?
Re: Why does EMS suck on my 286?

A definitive answer! Nice work. I was looking at ASPIBUF.SYS just now, and I saw that its INT 13h handler tests for the presence of Virtual DMA services and if there are none then it just falls through to the old INT 13h handler. So unfortunately it looks like this driver is only meant for protected …

16-bit DMA from 8237 is just 2 back-to-back 8-bit data cycle. The 8237 only has 8 data lines. The data lines on the 8237 are only used for accessing its internal registers. It doesn't actually read or write data during DMA. It only puts an address on the bus and sets the control/command lines, the …

Remember the Above Board is a 16-bit card, and it was doing the exact same thing. Ah. Didn't know there was a 16-bit version. According to the 1542 manual it uses the 8237 for DMA. I haven't seen anything that says you can't do DMA from one ISA card to another. Although it's hard to find any info, …
Re: Why does EMS suck on my 286?
Posted on 2019-08-10, 14:57
I think so, why not? For a 16-bit card to transfer to an 8-bit card it would have to test the MEMCS16 line and then split a word transfer into two bytes. That's assuming that the motherboard itself asserts MEMCS16 for system memory addresses, which is not clear. Even if this is possible the SCSI …

Re: Why does EMS suck on my 286?

Maybe the SCSI BIOS cannot transfer data properly from disk to the memory located on the EMS card. Either because of a software bug or hardware incompatibility. Especially if the SCSI card is 16-bit ISA and the EMS card is 8-bit ISA, trying to do DMA in that scenario may not be supported. Is there a …
Re: /3GB switch on 32-bit Windows

Not true, it's not limited to server applications or "background" processes. Here is the info from Microsoft . People are using the /3GB switch with Autocad and various games . Unfortunately for me, it seems that the /3GB mode is defective in Windows 2000 Pro and doesn't actually raise the 2GB limit …

When I recently tried to find a memory test program that ran from DOS, and which could test more than 16MB (unlike the old CheckIt), I only found two programs and neither one worked (just froze with no error). So I made my own: DOSMEMU -runs from DOS -uses unreal mode -tests the area from 2MB up to …
Re: Writing new software for the Mindset Computer, need help

Looks like the gfx modes are the same as the ST: 320x200x4bpp, 640x200x2bpp, 640x400x1bpp, plus an additional 320x400x2bpp option. But this system does not use the dreaded bitplanes?? The sound is also better than the ST. Maybe freddy can get ModMaster to run on a Mindset...

Goto the BIOS settings for the IDE and disable DMA, disable multiple sectors/block mode, and set to PIO 0. See if it becomes stable then.

/3GB switch on 32-bit Windows
Posted on 2019-08-01, 17:13
I tried adding the /3GB switch into BOOT.INI as a suggested fix for a game crashing. I also set the Large-Address-Aware flag bit in the game EXE, but it doesn't appear to do anything, for this or other programs. Task Explorer still shows everything being loaded below the 2GB mark. Is there any …
