Windows 98SE acting up on laptop?

Recommended Posts

The title says it all, I'm trying to figure out why my Windows 98 installation on my Dell Latitude D600 always acts so unstable. The CD rom will not work despite being recognized and changing the resources to avoid conflicts. Windows itself is extremely slow and "lags" just for simply clicking on a simple explorer window to display files.

What could be causing the issues
-Having 1gb of ram in the machine. Despite having 1gb of ram, my machine never failed to install Windows and drivers.
-The combination of VxD and WDM drivers? I've read somewhere having these two different types of drivers on windows can cause instability and conflicts. Since Dell did not officially provide drivers for my laptop there could be a possibility the different driver manufacturers created a different types with no intention of being used in the hardware combination of a Dell Latitude D600.
-The unofficially modded wireless broadcom driver by PROBL3MCH1LD (If that's how I spell his username). Another used has told me the card's taking up the first 32mb of ram can cause boot failure, although it never happened to me. The user fixed his problem by using rloew's ram patch and typing a certain command.
-Enabling ACPI? I've heard ACPI causes some issues on Windows 9x.

I'm so confident this could be fixed >o<

Use HIMEMX, it can make system more stable above 512MB.

Never install 98SE using ACPI. There's a reason IBM officially(!) says to install 98SE on my ThinkPad T40 in APM mode and not ACPI.

Do you have DMA enabled? Do drivers work in 32bit protected mode (no errors in the last tab in System properties about compatibility mode?)

Can you try different graphic drivers? I use Omega Drivers too, but you can try official T40 ones: https://www.techspot.com/drivers/downloadnow/3415/?evp=248e71de1f89703e55b98a0dba7e16bc&file=1

Try removing modules from laptop one by one (wifi card, modem, bluetooth, what can you) and see what removal makes system snappier.

Try changing every BIOS option you can, especially disabling all modules you can (serial, parallel, infrared, wifi, ethernet, among others).

Thank you! I will try this when I get the chance!

I installed Windows 98 without ACPI at first, then enabled it. Does that make any difference?
I do have a few compatibility mode issues: Generic Cardbus and Floppy Disk.
Never knew the Thinkpad T40 video drivers were compatible with the 32mb raedon 9000 card!

Disable ACPI in registry, it should be enough. I would better reinstall 98SE from scratch, setting the system up is half the fun after all :)

Did you have compatibility mode issues before you've enabled ACPI?

Haven't got to tweaking Windows 98 yet, but no, I don't believe so.

i wouldn't re-enable acpi, if you already installed with acpi disabled, then keep it that way. most computers will not work properly with the default acpi enabled on windows 9x systems, some might not even finish setup, i had run "setup /p i" ( acpi disabled ) on one of the sony laptops i have right now experimenting on windows 95. it uses ich3-m chipset. only some systems may function "properly" with the default acpi enabled. i use driver version "4.13.01.9066" for ("MOBILITY RADEON 9000" = M9_ENU, PCI\VEN_1002&DEV_4C66&SUBSYS_205817C0) which is used on the latitude d600 and inspiron 600m. 

i would make sure you have the right or adequate system.ini settings for vcache and maxphyspage. for 1 GB systems, you can use "maxphyspage=40000" and "minfilecache=44000" and "maxfilecache=44000". these are personally what i have used and my systems and about the minimum necessary for the vcache. it seems that when i used to use 0 for the filecache, it would cause the hard drive to stop working properly and run in compatibility mode after updating the system to a certain point, but when i used the proper vcache settings, it seemed to not have that problem anymore. 

some other solutions is to make sure the hard drive size is less than 127.5 GB i believe, it seems that on the last laptop build i did, the performance and functioned seemed rather buggy or slow and / or showed signs / had data corruption or related issues that apparently would occur if running on partition sizes 127.5 GB or larger. for the broadcom wifi, i dont remember what configuration i had on the dell latitude d600 or inspiron 600m, but i personally had more success, at least recently, with using the realtek 8185 mini pci wifi card. it works well on the dell precision m70 and might work on the latitude d600. i had problems running the bcm4318 on the precision m70 and i think another laptop with inability to boot.
