I have a Quantium HD and have FDisk, format and when I start the setup, when It starts the setup it lockes up at the win98 splash screen, I also tried installing win98 to the HD and started setup from the C.win98 directory but it does the same.I also ran scandisk (Complete) and had no errors. This computor was working fine in the past but started locking up alot so I decided to reinstall the O.S. I hav tried 4- 5 variations of Format ,(Format C: ,

Two main components in any PC are always going to be at risk of having failures. The HD and the RAM.
I know that I have a few bits in one of my RAM sticks that are playing up. The program freezings and odd behaviour pointed me to this because it was not one program but any program at random, and whichever program crashed on me, was working in the dodgy RAM area.
I ran MEMTEST86, and it confirmed my suspicions. For the HD to lock at the same point everytime could be a bad drive, or indeed it could be RAM. To eliminate the RAM, get hold of MEMTEST86, and let it test the RAM. For the HD, beg, borrow or steal another one. You might also try FIXMBR on your HD to reset the boot sector. Formatting does not do this. Use a boot up floppy disk to effect this.
Of course these two items are not the only things that can go wrong, but I am basing my prognosis on what you have reported.

Locking up on the LOGO makes me believe that WIN98 installed, but is having trouble working in RAM. or through a bad sector on HD.

Safe Computing...:o)

a lowlevel format would fix the boot sector
it would change all the data in the disk back to zeros
if it did not come with the hdd
then you can download it from the manuf. web site
have your drive model# handy
this soft ware will also tell you if there is anything wrong with youd hdd and fix alot of problems that any os's won't

Thanks guys ,I'll get to tring your suggestions and get back to you.
Chrisman.7, does HDD mean HD drivers?

hdd means hard disk drive

I swapped mem , installed new HD ,ran fdisk format C: /u /s and rebooted . When it boots up the win98 splash appeares and freezes.

Tried the same process as above and after I got to E:I started setup to install win98, after scandisk ran and found no problems setup started installing then an error popped up ,,,Standard mode: Bad Fault in MS-Dos Extender. Fault: 0000 Stack Dump: 0000 0000 0070 Raw Fault Frame : EC= 0000
Does this point to the problem ,,if so what ???

i did a little research on the at other forums one in germany from what i could gather said that windows did not fully load onto the disk

another said: Main memory defectively or not correctly put in slots

here's another:
Standard Mode Messages
If you get any of the following error messages, remove any memory managers (such as EMM386.exe, QEMM, or 386Max) from your Config.sys file, and then run Setup again.

Standard Mode: Invalid DPMI return.
Standard Mode: Fault in MS-DOS Extender.
Standard Mode: Bad Fault in MS-DOS Extender.
Standard Mode: Unknown stack in fault dispatcher.
Standard Mode: Stack Overflow.

NOTE: If you still have problems, add EMM386.EXE back into your Config.sys file and exclude all ranges. For example,

device=c:\windows\emm386.exe x=A000-FFFF

If you encounter these messages or if your computer stops responding during Setup, turn on double-buffering in SmartDrive. Several SCSI hard drives and some ESDI drives require double-buffering.

To turn on double buffering, add the following line to the beginning of your Config.sys file:

device=c:\windows\smartdrv.exe /double_buffer+

where "c:\windows" is the path to your Windows directory.
the web site for the last one is:

I really appreciate all the help but I 'm not getting you to understand my situation.
I have tried 2 differant HD's 2 sets of memory and run fdisk& format many times and in many veriations (format C: C:/s C:/u /s etc.) WIN 98 2ed will not install, it wont get past checking files to run setup and freezes, I've tried running setup from the cd rom & I installed the complete disk on the HD in a C:\win98 dir and ran setup from the C:. Either way I get the same results. When I start setup it starts as normal to the point as soon as it starts check system files to run setup it freezes, one time it went to the first win98 splash screen. Thats where I'm at.

it's possible that you have a bad memory slot
