Remarkable job. Respect! That's a fine laptop for Win98/DOS. I've dealt with quite a few Toshibas. The only thing I don't like about them is the screen stretching because it deforms the pixels unless you are running the LCD at the highest resolution

After struggling with tutorials in different languages, trying to find files with broken links, learning how this process is in general (I had no idea at all), with lots of fiddling and some luck, I managed to get the 06B4 microcode (latest Tualatin) into the 7.5 (latest version) BIOS for this …

In comparing the datasheets, it looks like the 512KB chips have much tighter tolerances for voltage. The tolerance for clock stability is also tighter, don't know what other differences there are. Surprisingly they don't show any appreciable difference in current draw. Bigger cache makes a huge …

hey guys I have a NF7s v2 that sadly doesnt post.. and gives a black screen. I have tried all the discharging tricks, different psus, ram sticks, video cards and different slots of the last two and narrowed it down to it possibly being a corrupted bios. It gives the correct beeps when there is no …

I used SCROLLit for scrollback, you can find it here: http://ftp.mpoli.fi/pub/software/DOS/UTILS/SCREEN/ . It lets you select lines and save them to a file. Naturally you can use it inside a DOS session in DESQview or Windows to scroll back an individual DOS session's history, then use DESQview or …

Thinking out of the box, if you have a i815e(p) based Tualatin ready board, I would go with that unless you need the PIII-s also to run demanding WinXp applications which require 1GB memory. It's not a solution for your main issue, but it's a shame not using the Tualaking :). You are right my …

If this makes sense... According to this source and the Tualatin datasheet I would have to connect the BSEL1 to a 3,3v pin (but... isn't it grounded?). I'm not sure and I don't want to toast it. I would try this with a Coppermine 133MHz first anyway to see if it works but only if an expert from the …

Required voltage is lower, but the power draw in Watt is higher for Tualatin. Still not huge numbers like the P4, the onboard VRM should be able to handle the 32W at 1,5V if it supports the other Tualatins. You may have a point here. You say the Tualatins draw more current? It could be, but as you …

I have seen this before, certain boards (officially) did not support the Tualatin with 512KB cache. It's quite puzzling, because this board (allegedly, according to the site I posted) supports the PIII-s 1.26 GHz (which also has 512k of L2 cache). The Shuttle AV18 (AV8? whatever it is) doesn't list …

Hello guys, I'm putting together a Socket 370 system, aiming at the best from that era. The Motherboard is a MSI 694T Pro VER 5.

Thanks for the answers guys, neither of them is exactly what I'm looking for. Like I said, I'm looking for something like GNU screen or tmux, text only.

Is there such a thing as a terminal multiplexer such as GNU Screen, Tmux, etc, for DOS? What's the closest alternative? I read that there was an attempt in the early 90's called Twin but was soon abandoned because DOS lacks multi-tasking. My main objective is being able to scroll (scrollback buffer …

Nice, interesting. Any hex editor would do? Is there a "standard" one? I was thinking to use this process to flash a XT-IDE binary and then use it with a network card on an old computer.

I suppose bad sectors on the hard disk might cause the issue because the disk will keep retrying until a timeout is reached. But this would probably last longer than a fraction of a second. I had a similar experience on a HP OmniBook, though. (P3 1GHz so similar age.) The battery wasn't holding a …
