Dell System 325 Replacement ROM BIOS chips

I have a legacy Dell System 325 that I need to restore. It won't boot. Where can I get replacement ROM chips with original Phoenix Plus version 1.10 X48 ( January 1988) BIOS. The system is Processor 80386 Math coprocessor 80387 Version A01-034A. The chips are two 28 pin DIP ROMs (ROM 0 and ROM 1 ). There are stickers on the chips:

Dell Computer Corporation
P/N 20852 1
Rev A01 4-W15

Dell Computer Corporation
P/N 20852 0
Rev A01 4-1-W15

I think I only need the BIOS file and replacement chips, and somebody to flash them?

Anybody can help me? Thanks.

Dell technical support chat no longer acknowledges my servce tag number. Says they were expunged( from their data base I guess).

Why do you want to resurrect a dinosaur like the 350? You will never find a replacement ROM. I am assuming this is an actual computer with a hard drive and not a smart terminal. Just getting the ROM will probably not do it, as you don't know if there is an operating system on the hard disk and if the hard disk actually works or if all the parts work. These old computers are not like vintage parts like some old cars

Is the motherboard battery as old as those chips?

sentimental, it was mine originally.  Everything should work except for the ROM chips.  It has DOS 6.0 and Windows 3.1 for Workgroups..

original CMOS  battery was a Raytheon 410 ( 4.5 volts). It was replaced at least once and the OEM is now obsolete. I made my own out of 3 AAA rechargeables and a battery holder for $3.
