Amd Socket A cpu and Vm

Microsoft Windows 98 se (full product)

Specs: Windows 98 SE
Recent suggestion to us Vm instead of dual boot for Win98 & Xp.

Downloaded the Ms Virtual Pc and find the cpu wont support the VM.

How can I determine which CpU's are compatible with ECS mobo 741-GX and also Vm compatible? The current cpu is AMD 1.05 Sempron.

Thank you.

There is no such thing as a 1.05GHz're running your CPU at the wrong speed. All Semprons run at 333MHz FSB (166MHz frequency) so your CPU is probably supposed to run at 1.75GHz (10.5 x 166MHz). Get that straightened out before doing anything else. Go into the BIOS & change the CPU frequency from 100 MHz to 166MHz. Save your settings & exit.

I suggest you go with the dual boot setup, not VM. Start by wiping the HDD, then create at least 2 for 98 & one for XP. If you want 98 to be able to access the XP partition, both partitions must be formated as FAT32. And it's almost always best to install the older OS 1st.

Install Win98 on the C: partition. Make sure you have no more than 512MB RAM when doing the installation. After 98 is fully installed with all drivers & updates, tweak the vcache settings so that you can use more RAM.

Once that's finished, boot into 98, then pop the XP disc in the drive. When the screen pops up asking if you want to update, select "Advanced" & direct XP to install onto the 2nd partiton.

That's all there is to it.

BTW, that's a horrible motherboard you got there.

Well the plot thickens. Deciding not to upgrade mobo I opted to increase the ram to 2gb and a larger Eide HD.

Installed the new ram and where dual boot to W98SE was good, the os now crashes, been chasing this issue on another thread.
Migrated Xp to the new Hd and bootmagic to setup 2nd os ( just as i had done originally) but w98 will not boot indicates not enough memory. The same problem occurred on the original Hd with the dual boot after ram upgraded from 1 to 2gb. Have modified cache to 512 mb.(BTW win98 was only so I could view/modify sony mavica mvc1000 media without having to finalize the mini CD.)

Granted ECS may not make the greatest mobo but at this point I'd hate to pitch the $75. for the 184 pin ram.

My system is reporting the CPU as 1.05 GHZ, but it seems like I purchased something like 2.5 GHz five or six years ago.

Thank you.

That makes sense...a Sempron 2500+ runs at 10.5 X 166Mhz. or ~1750Mhz.

Post back your vcache settings in 98.

My comment wasn't a knock against ECS, it was a knock against the crappy SiS chipset the board is based on.

Check your BIOS settings, your CPU is configured incorrectly & I'd be willing to bet other BIOS settings are wrong as well.

I have run MS Virtual PC on many an old system. A VPC 2007 only needs a 400Mhz processor.

You can also use VPC 2004.

Sorry I suggested it. :(

yea I have run this on a machine with a 1.3 duron, with a linux OS and 2gb of ram

its the ram that important and, with 2Gb you should have no problem. Although I do prefer a dual boot setup. Maybe instead of Xp and 98, how about XP and mint.

Jam I think you gave my cpu a good kick, I found the bios setting @100 mhz, changed to 166mhz as you suggested and system reports cpu 2500+ 1.75.

Also follwed the MS bulletin and set MaxPhysPage=40000 and intially set Vcache to 524288 minfilecache 32768 and was able to boot Win98 as dual boot - using bootmagic to select active partition.

Note for other Win98 user boot up problems, the Vcache configuration alone( W/ Ram > 1GB) didn't allow win98 to start, but adding the MaxPhysPage=40000 with Vcache specs did.

Still a few bugs, but at least dual boot is working.

Thank you for the help!
