Good morning,
Did I miss something or maybe I do something wrong but since the new version of the core, while the Tandy & JukoST bioses work like a charm with the HDD that I've created (following the std rule as you explained), this same HDD is not recognized at all by other Bioses, even the TurboXT does not recognized it on my side. (Of course I used the new IDEXT) It is annoying because I do not use anymore JukoST for the mouse issue as you know.
Well, I can of course use the Tandy core which works fine but if I want to have a "standard" PC-XT then it won't work.
Any idea ?

Has ide_xt rom in the repository been replaced by a new one?
Maybe pcxt_micro8088.rom or pcxt_pcxt31.rom has the old ide_xt rom embedded in it?

I apologize, while I was thinking when I built the Bioses that I was using the new XTIDE, I in fact used the old one. I copied the wrong one in the folder where I put the .BIN...
I've just repeated the operation (with the new XTIDE at the right place ) and now everything work as it should. Very sorry..

@flynnsbit, your guess was true

Every day at midnight there was a race to dial in to the BBS at just the right moment so you would get more turns to play for the new day. What about Prodigy?

There is no UART OSD option... so

I'm guessing this is needed in the core to enable the option:

Code: Select all

localparam CONF_STR = {
	"PCXT;UART115200:115200;",

Yes, it works!

Anyway,

I just manually started the TCP modem emulation via SSH

Code: Select all

#midilink TCP BAUD 9600

Thanks for adding this feature as there are quite a few users of the TCP modem - and NML32 can play online Wordle clones

For dummies

ATRZ

  [RETURN] / [SPACE] - Next page of results
  "P" - Return to pervious page of results
  "Q" - Quit without making selection
  "-" - change to parent directory

It also doesn't perform much better than how it was previously set, which was based on 14.318Mhz... so if this starts to give problems and is difficult to resolve, we could consider going back to 14.318Mhz without cycle accuracy as the maximum speed. Although now, with this speed, for example in Monkey Island, animations come out, like the pirate hanging from the lamp in the bar.

2. As for EMS, now A000 cannot be used as EMS memory frame, only C000, D000 or E000 as reflected in the OSD menu. The reason is that some games use that segment to detect the presence of EGA/VGA, and they do it by writing there, so it could overwrite essential content, and the same when used as UMB memory, that's why I also offer the possibility to disable it from the OSD menu.

In addition, the E000 segment cannot be used for EMS either and we have XTIDE in EC00. In order to use it there, XTIDE can only be embedded in the BIOS at offset F000 and writing to EC00 must also be enabled. Ultimately, it is best to use C000 or D000 for EMS, indicating it appropriately in the OSD menu.

#2, What is the right config.sys entries now for both UMBS.SYS and LTEMM? The way I did it?

DEVICE=C:\USE!UMBS.SYS A000-AFFF D000-EC00

DEVICE=C:\USE!UMBS.SYS D000-EC00

Code: Select all

DEVICE=C:\USE!UMBS.SYS A000-AFFF D000-EC00

Using the A000 segment has that small risk that I mention, minimal but there it is... that someone will overwrite it. To avoid that problem, and also that nobody detects anything related to EGA/VGA, I advise you to disable it from the OSD menu and leave this line like that, even if you lose 64Kb of UMB memory:

Code: Select all

DEVICE=C:\USE!UMBS.SYS D000-EC00

But as I say, the risk is minimal, and it could be left that way too:

Code: Select all

DEVICE=C:\USE!UMBS.SYS A000-B000 D000-EC00

Setting B000 does not imply that this segment or its beginning will be used for anything, but it marks the limit where it should no longer be used... therefore, B000 is better than AFFF.

DEVICE=C:\USE!UMBS.SYS A000-B000 D000-EC00

many many thanks for all the work you do to get this core working !

I am struggeling directly with the Quick Guide from here: https://github.com/MiSTer-devel/PCXT_MiSTer#quick-start

I have removed all PCXT configs from my MiSTer to start from Zero.
I run Update_All to get the latest MiSTer from the 24-11-22 and the latest PCXT Core, also from the 24-11-22.

I downloaded today (25-11-2022) the full PCXT Repository from MiSTer-Devel as ZIP and extracted the following files..

Code: Select all

\games\PCXT\hd_image.zip\Freedos_HD.img (had to change the extension to vhd to get it detected by the Menu)
\SW\ROMs\ide_xtl.rom (md5 26be1c20dec0d626b574f0ef82febf62)
\SW\ROMs\pcxt_micro8088.rom (md5 408f5825ed469e73ec4e54fe7c98f2b0)

I moved the files to MiSTer \sdcard\games\PCXT\ and started the Core.
I followed the Quick Guide from the PCXT Repository and got the following shown...

IMG_8532.JPG
IMG_8533.JPG


But here the system stops, the cursor is blinking but nothing more happens.
Any Idea why? Do I miss something .

Maybe someone can explain
Note 2: It is also important to update all ROMs based on the new XTIDE BIOS, and located in the folder "..\SW\ROMs"
to me. Do I have to update some ROM files manually?

Btw, there is a second "pcxt_micro8088.rom" within the ZIP of the freedos VHD which has another checksum.

Thanks again for this Cool-Core
