Hello,
when I try to install OS/2 2.0 on a PS/2 55SX (386SX 20, 4 Mb RAM) with ESDI hard drive (geometry 762/6/26 like the real hardware), PCem v14 crashes with "Bad Attention Request 03".
Crash happens when HPFS formating drive.
Can someone confirm this is a bug ?

[Request] Improve Hard Drives timings
Hello, I see recent improvement on cdrom and video cards timings and I think it could be interesting to see the same improvement for hard drives. Cause even on slowest MFM drives (8 bit controller, access time near 100ms and throughput lower than 1 Mb/s), PCem format and access drive really fast. I ...

Hi, Sarah : can you explain me why you did this svga->hwcursor.addr = (0x1fc000 + ((val & 0x3f) * 256)) & svga->vram_mask; instead of svga->hwcursor.addr = (vram_size-0x4000) + ((val & 0x3f) * 256); as the first prevent an hypotetical 4 Mo display memory ? The docs says that the hardware...

[request] Implement onboard chips emulation
Hello,
I don't know if it's difficult to do but some emulated PCem boards (Intel Advanced/EV for instance) have onboard chips that aren't emulated : S3 Trio 64V+, SB Vibra 16.
Is it possible to add onboard chips emulation for future version please ?
Regards.

And how is this frequency simulated with pcem ?

VCLK question
Hello,
Can someone explain how multiples VCLK is handled in Pcem ?
I found out (or maybe i'm totally wrong) that there is one svga clock and two fixed const but in case of more ?

i would like to know if there is code in PCem that handle SMM/SMI ?
SMM is mainly used by APM and some OEM code : http://opensecuritytraining.info/IntroB ... %20SMM.pdf

Re: Suggestion : add GUS MAX and Crystal soundcards
So no one is interested in theses cards ?
I finally succeded in launching Win 3.1 with GUS MAX driver. But this leads to another problem as samples are playing in a continuous loop. I probably ovelooked some latches.

Re: Suggestion : add GUS MAX and Crystal soundcards
@omarsis :
cause it shouldn't be too hard to add as CS4231 is really close to the AD1848 that PCem already emulate (as part of WSS) and Crystal sound cards (4231/4232/4236) can be found on many boards.

[Patch] Suggestion : add GUS MAX and Crystal soundcards
Hello, first, as a warn, i'm no programmer, so don't blame me for what you will read below. I think that PCem could add GUS MAX support as nearly everything is already emulated : a gus MAX is classic GUS with the addition of a CS4231 Codec (WSS). I read the GUS SDK, a CS4231 tech sheet, compared wit...

Re: Improving the AWE32 emulation
Nice Job !
May I ask how did you determine that, for instance, Impulse tracker tests the non variability of the LS byte and the variability of the MS byte to identify the AWE32 ? Reading through ASM code ?

Ok. I didn't know that by default OCP uses SB16 mode . The problem can be reproduced by explicitly selecting the AWE32 output.

Hello,
you have to make sure that PCem support your motherboard chipset ("soundbridge / northbridge"). It's not just a BIOS matter.

Problems with 16-Bit DMA ?
Hello,
I'm trying to put Ultrasound on 16 bit DMA but setup test keeps failing : Pcem detect that it's a 16-bit DMA (here dma channel is 0x5), but I can't go any further.
Is the GUS test accurate for 16 bit DMA or not ?
Thanks.

Ok, thanks Sarah.
PCem is no more crashing in rev763.
But, conflict is still there and RLL/ESDI is unbootable even with the right nvr file.
I use BIOS PN 33F8152 (11/02/88), model F8, Submodel C, Revision Level 0, Ref Disc 1.05. Which version do you have ?
