Does anyone know if it's possible use Cassette BASIC to get an assembly language program in memory and jump to it? It's something I've never looked into. This is possible on an Apple II (something involving negative line numbers if I remember right), and ADTPro uses it as part of the bootstrapping …

It wasn't any better with a Pentium 100, no mobo cache, and 8MB ram. The 3.11/95 transition gets my vote for the worst Microsoft OS transition. Hell, my friends and I would still talk about how much it sucked in 2001, so much so I was a bit afraid of XP. The official requirements of XP too were …

I think you're right. I feel like an AMD K6 for your existing machine would approximate it pretty well too though. It's interesting the time period you mention is also right around the time the Celeron came out. I feel like other than gamers/custom builders, people running Windows 95 toward the very …

Haha I don't mind answering as you are giving me a lot of nostalgia for around 10-14 years old. My guess is you need to add in config.sys: device=c:\dos\emm386.exe noems and reboot. I'll leave it up to you to research the meaning behind this and the other things/tweakage it lets you do. But boiling …

I've done one of these lubrications+gear replacements on an old Mac floppy drive. The auto-inject ones are quite complicated with lots of springs and panels to be taken apart in the right order. I used spray lithium grease and was kind of amazed how well it works. The thing ejects the disk almost …

Hey Cesora, Since I just posted on another CD-ROM question I thought it worth mentioning. Even if you get an IDE CD-ROM a Pentium 200 is right on the edge of where the BIOS may or may not have support for booting from CD-ROM. That sounds like the era of Award bioses. If you have BIOS version 4.51PG …

It sounds like you got this fixed but I wanted to add something that causes a very similar, infuriating problem. Some AWARD bioses have an option for virus protection. If you enable it, the bios tries to prompt you whenever a program writes to the C: boot sector. The problem is that the Windows 95 …

Before bootable CDs the bios didn't know or care about cd-rom drives. What OS are you running? In Win95 it should just work. For DOS you need to find an atapi cd driver and load it in config.sys. oakcdrom.sys and xcdrom.sys are common generic ones for atapi (IDE) cds. Then you need mscdex in your …

Around 1995ish I was using a new 486DX2-66 with 4 MB of RAM & WfW 3.11. The manufacturer had an offer for a Windows 95 upgrade CD which we got. I hated it! The swapping. My little educational math games were so slow. Not knowing that the reason was that 4 MB was totally unrealistic for usable Win95. …

It's weird. For my system when I use the win98 disk and start windows with cd drivers booting from cd it sees my cd drive fine. Once windows actually boots up it doesn't see it anymore. Windows 98 shows that it has IDE controllers for each of my sata inputs but has an exclamation point on it …

Let me guess, a CDD461 or CDD462 on a CM-153 interface card ? I looked at those on Google images and it didn't look like them. The front was significantly bigger than the CD tray and the only button was a (large) eject button. I forget how I came across the drive. I think it was bundled with one of …

Won't that cause disk corruption issues when switching between MS-DOS and Windows(using Akt-Tab)? If a disk write/read gets broken up and Windows(because it gets control) is switched in and changes things on the hard disk, the MS-DOS app won't know and the both of them might corrupt when reading/ …

I'll add, if driver+mscdex work, that will be a way to at least make it accessible in Windows until you find another solution. I once had one of those Philips external drives with a proprietary ISA controller card that I used this way.

I don't have answers but I'm curious whether an atapi CD driver and mscdex work in DOS mode? I thought the whole point of IDE compatbility mode was to be, well, IDE compatible. So you'd think it would at least work slowly under Windows. Maybe windows has a whitelist of pci ids or something and it …

If you're going to put in an ISA sound card, I'd go ahead and narrow down and say it will be DOS/98 based. It's DOS games where having a true Sound Blaster compatible (with working ISA DMA) is helpful as XP games will use Windows drivers and therefore be neutral to what card you actually have. A …

Debug will read from stdin if you want to do it that way. I'm surprised no one has chimed in about this though, you'd think if all Toshibas of this model worked this way it would be widely known.

Yes, weird. I wonder if the BIOS settings are stored in the boot sector rather than in CMOS or something. DEBUG also has an e command you can use to overwrite things in memory. You could try to use that to write an F8 at 40:00 and an 03 at 40:01 and then exit and run msd. Even if this works, it's …
