the problems occurred when customer tried to start internet after installing adsl-modem. he told me he has 2 antivirus scanners.
somemone told one or both of the sdram are defective 128 + 64 mb sdram. i will check them tomorrow.
the following errors are showing at boot-up
c:\windows\ifshlp.sys is lacking or defective
also c:\windows\system\vmm32.vxd
i did not yet open the case. its is showing intel 440 bx pentium III 500 mhz
2.1 gb hardddisk
customer did not change anything since it worked but harddrive and cd-rom are connected to the wrong channels. hdd is secondary master and cd-rom primary master. does this have any affect?
i have used the startdisk and customer made scandisk. some defective parts can be seen. one of a long-name-file cannot be repaired.
dos does not show a windows-directory. is it inside a dir00010 etc.? i cannot activate scanreg /restore when i close the help-file.
some unknown-files have to closed or editor has to be escaped to be at dos-prompt. scanreg/restore does not work. i cannot see scanreg anywhere. i will check this out on my machine.
virtual disk(d) is created and e: is cd-rom-drive. when starting setup scandisk is started and windows hangs in the first minute with saying there is already a windows exisisting(su0168). to my knowledge its the clear error for ram-problems.
i will check rams and anyhow try to repair. later we will buy a new harddrive and save data to the new one.
scanreg is working on my machine but not in customers. it says no file found.maybe this problem occurs because the hhd is on the second channel.
but c: contains the original files.
