Oh, Neat. I did not see the "evolved romdos" rom there. That's a very fancy stacked PCB it has there.

That, (your RW-XT-001), is basically an IDE hardcard, but with a compact flash module baked on instead. CompactFlash is designed to be electrically identical to IDE. That makes it more useful than a paged ramdisk, like this is, as it can work with any OS that knows how to communicate with an IDE …

A quick peek inside the romdump suggests a csrd ID and a manufacturer. "Copyright (c) 1993,94 by MTB GmbH - RAM-/ROM-Disk RARODI-1 V1.3" MTB GmbH makes aerospace and scientific equipment, and still exists. No current public facing data exists on this old product that I can find. The identity string …

I'll necro an old thread, just for the sake of this page being indexed by google, and people landing here, even if the OP never reads it. I've seen similar cards, but not that specific card. It's a 'ROMDOS' card. Usually a 1mb or so ROM, that maps into the adapter rom region, and then has some …
Re: [Win98SE] Drives are in MS-DOS compatibility mode, but why?
Posted on 2023-07-28, 10:29
Well, was worth a shot. Another thing to check is in the system.ini file. There's options that can be set in there that will disable 32bit disk controllers. it would be in the [386Enh] section, and would be "32BitDiskAccess=Off" if that is present, 32bit disk access will be turned off. I dont know …

Re: Were you ever hurt by a computer?
Posted on 2023-07-24, 07:23
More times than I care to remember. Back in the "wild west" days of PC computing (80s to 90s-- ESPECIALLY in the 90s), computer case chasis often had sharp metal edges inside, as they were mass-manufactured, with corners cut on some quality controls. Packard Bell "Pizzabox" style systems were …
Re: Information on 'imaging' a hard drive, please.
Posted on 2023-07-23, 21:24
IIRC the xbox 360 requires a specific type of drive with custom firmware, you can't just clone the data to any old SATA drive and expect it to work. Might depend on the console; but the old fat ones with the HDD caddy on the top of the console, just check for an actual bonafide PNG image (which is …
Re: How can i prepare Windows (98 or xp) to boot on every motherboard for testing them without new installation?
Posted on 2023-07-22, 19:59
It's possible to create a ramdisk based win9x deployment for use with a USB stick or with a CDROM. You'll need to create a generic deployment of a reasonable size (at least 300mb for win98), using a virtual machine, and using a flat image type disk image. I'd suggest using drivespace3 to compress …
Re: What modern activity did you get up to today?
Posted on 2023-07-22, 17:51
It seems to be working well so far. Nylon prints at a very high temperature (253C, in my case. My printer alarms higher than 255C), which is above the melting temp of the rosin. I put the mix in a spray bottle and misted the bed with it, and then heated the bed up to 80C for a few minutes to dry the …
Re: MT-32 LETTER Font (not soundfont) for recreating the MT-32 front plate ?

the .AI files might be convinced to go through ps2edit and get spat out as an .IGS file for my CAD software. Please hold... OK. Here is a 3D object created from the illustrator files.

I'd be more apt to just trace it with CAD software if you have a good scan of the bezel. I can make a quick and dirty .STEP and .STL combo for you, if you can find me a good scan (as in, put inside a scanner)
Re: What modern activity did you get up to today?

Modern activity? I finally am getting around to testing out pine rosin powder (dissolved in isopropanol) as a bed adhesive for printing with nylon. So, basically playing with the 3D printer today.
Re: WIn98SE system DOS mode: EMM386 only gives 31k UMBs!
Posted on 2023-07-22, 15:06
I just looked at the output of MEM/D and found that, other than the monochrome video buffer, I only have 4k of Upper memory at CF00. I also tried MSD from the DOS prompt, and apparently, I don't have it. Where can I get it? BTW, I still have QEMM on my machine, and the Windows drivers seem to work. …
Re: WIn98SE system DOS mode: EMM386 only gives 31k UMBs!
Posted on 2023-07-20, 06:53
EMM386's RAM and NOEMS directives can coexist fine. It will create UMBs but not set a pageframe. Depending on the chipset, UMBPCI + HIRAM might be a better option in that case though. I've been noticing on a lot of mid 00's laptops, that there are 'important things' living between D000-D3FF, and …

I would need to see what your memory map looks like without any memory managers loaded. (No himem.sys, no emm386.exe) I need to see what the adapter rom region looks like when it is untouched. I could then offer suggestions on where or how to do manual include statements. You can get MSD as a stand …
Re: SBEMU: Sound Blaster emulation on AC97

I am going to suggest that maybe the issue is related to the wonky hardware in that toshiba laptop. I say this, because the exact same configuration (minus the memory area specific tweaking) on my Dell XPS 15, works like a charm with the same games that crash spectacularly on the Toshiba. The Dell …

Adding here: I have an old mid 2000s era Toshiba with 2GB RAM, and AC'97 / ICH audio. SBEMU finds it fine, and it seems working but I have run into some strange issues. I am unsure if it is related to strangeness of this machine or not: This machine has a very strange memory map setup, and appears …
